The Underlying Motivations and Long-Term Trends of the US Decoupling of China-US Science and Technology Relations

Since 2018,the US government has adopted a range of restrictive measures on China-US science and technology exchange,as it strives for a decoupling strategy against China.This strategy has brought about historic change in China-US science and technology relations.The US government has set out to obstruct the free flow of technology,data,capital,markets,and talents between China and the United States,thereby changing the basic rationale of China-US science and technology cooperation.The US has multiple underlying motivations for implementing this strategy including recognizing the security threats posed by China’s cutting-edge technology development,treating China as a competitor in global science and technology diplomacy,prompting the backflow of the technological industrial chain,and the strengthened industrial competition between the two countries.Decoupling is one of the competition strategies of the United States.It is aimed at ensuring a favorable position for their national innovation systems,particularly in China-US competition.However,the limitations of the decoupling strategy may not allow the US to achieve what it desires.These limitations also provide space for the two countries to ease their competitive relationship.

China-US Trade Relations:Win-Win Picture Distorted

At present China-U.S.trade relations are in a state of confusion.Although both countries have gained tremendous benefits from the bilateral trade relationship,some Americans have intentionally distorted some basic facts regarding China-U.S.trade relations. Based on an analysis of some official and nonofficial research reports published in the United States,this article holds that the China-U.S.trade imbalance is the symptom of a bigger issue stemming from the contradiction between the United States as the world's sole superpower and China as an emerging power.Economic globalisation came about due to the needs of western developed countries represented by the United States to boost economic development.Only by seizing the opportunities of economic globalisation, has China gained strong economic growth. Such a development is changing the world political,economic,military and cultural landscape that have been shaped since the post-cold-war era,and has to some extent raised doubt or suspicion on the part of the United States and its western allies.This is a manifestation of how unprepared some people in the United States and other western countries are in the face of China's rapid development and rising status.So,their immediate reaction has been to seek protection for themselves,and try their utmost to prevent China's rapid growth from impacting on the international framework and their vested interests.

Trumponomics and China-US Economic and Trade Relations

Since he took office, the new US president, Donald Trump, has unveiled his broad economic policy--now called Trumponomics. It emphasizes neoliberalism at home, less government regulations, more growth and weakening the welfare state. Intemationally, Trumponomics embraces protectionism and nativism with a focus on US economic interests. Trumponomics caters to the lower-middle classes, a reflection of the country＇s current economic and diplomatic challenges. Trumponomics will bring uncertainty to China-US economic and trade relations. China should carefully study the policies of the Trump administration and prepare contingency plans.

US Competitive Policy toward China and Transformation of China-US Relations

The door to strategic competition between China and the US has opened under the Trump administration, whose strategy, policy and tactics toward China create a grim picture for bilateral relations in the short run. However, the relations in the long term depend both on the state of interplay between various parties in the US, and more importantly on China’s influence and response.

A Review of China-US Economic and Trade Relations (2007-2015)

In order to find indications for future bilateral relations, it is worth reviewing the development of China-US economic and trade relations in recent history. Generally speaking, the nine years between 2007 and 2015 saw non-stop progress in China and US trade and economic ties. The China-US interdependent and complementary economic and trade connections ensure that bilateral relations are constantly developing and merging following their interdependent paths;the global challenges, such as the financial crisis and recent extreme weather events, have allowed China and the US to be in the same boat,weathering these different forms of turbulence. Decisions on important domestic policies and disputes can now be discussed earlier and effectively following on from the construction of multi-dimensional crisis management mechanisms. But undeniably there are unsettled and conflicting points in their relations, such as the fact that the US strategically excludes China from its free trade agenda, not willing to accept many everyday items manufactured by China. This is a major obstacle preventing their relationships deepening. History tells us, in future, if both sides could have a bigger vision, relations would better develop, for the new type of major power relations and the subsequent road would be less rocky and bring more benefits for the peoples of both countries.

A New Model of China-US Big Power Relations： A Symbolic Sign in Foreign Affairs

To cope with the current crisis and tensions full-filled China-US relationship, Chinese President Xi Jinping put forward the concept of building a new model of China-US big power relations, which the US agrees. Yet the new model won a heated discussion. In China this new model was evaluated positively and optimistically, while in the US it was perceived as a strategic challenge or even a threat. In the present article, the author proposes that this new model of China-US big power relations is more like a symbolic sign in foreign affairs rather than a strategic challenge or a threat or an effective and workable mechanism at this moment, and meanwhile analyses this view from diachronic and semiotic perspectives. The analyses reveal that the new model functions as a symbolic sign, signifying to the world that conceptually the two big powers have a good and harmonious relationship.

Robust Radiometric Normalization of the near Equatorial Satellite Images Using Feature Extraction and Remote Sensing Analysis

Relative radiometric normalization (RRN) minimizes radiometric differences among images caused by inconsistencies of acquisition conditions rather than changes in surface. Scale invariant feature transform (SIFT) has the ability to automatically extract control points (CPs) and is commonly used for remote sensing images. However, its results are mostly inaccurate and sometimes contain incorrect matching caused by generating a small number of false CP pairs. These CP pairs have high false alarm matching. This paper presents a modified method to improve the performance of SIFT CPs matching by applying sum of absolute difference (SAD) in a different manner for the new optical satellite generation called near-equatorial orbit satellite and multi-sensor images. The proposed method, which has a significantly high rate of correct matches, improves CP matching. The data in this study were obtained from the RazakSAT satellite a new near equatorial satellite system. The proposed method involves six steps: 1) data reduction, 2) applying the SIFT to automatically extract CPs, 3) refining CPs matching by using SAD algorithm with empirical threshold, and 4) calculation of true CPs intensity values over all image’ bands, 5) preforming a linear regression model between the intensity values of CPs locate in reverence and sensed image’ bands, 6) Relative radiometric normalization conducting using regression transformation functions. Different thresholds have experimentally tested and used in conducting this study (50 and 70), by followed the proposed method, and it removed the false extracted SIFT CPs to be from 775, 1125, 883, 804, 883 and 681 false pairs to 342, 424, 547, 706, 547, and 469 corrected and matched pairs, respectively.

Promoting China-U.S.Arctic education cooperation:challenges,opportunities and recommendations

Arctic education refers not only to the teaching,but also to research,communication,dissemination as well as popularization of knowledge related to the Arctic.This article reviews joint efforts between Chinese and American educators and researchers to promote cooperation and understanding in Arctic education and research,and examines the facing challenges of China-U.S.Arctic education cooperation which include current political or economic tensions between the two countries,the differing perspectives and priorities on Arctic policy,the disproportion in Arctic scientific research,different research methodologies and discourse system in social science.This article also argues that there are opportunities for the two countries to cooperate in Arctic education.Common goals and interests in the Arctic,Arctic-dedicated institutions with significant Arctic research capabilities and partnerships around the world provide foundations for Arctic education cooperation.The implementation of a new science-based Arctic treaty of the Arctic Council is an opportunity for China-U.S.Arctic education cooperation.As for future cooperation,it suggests that in addition to promoting the direct bilateral cooperation,cooperation within international cooperation platforms and mechanisms,especially within the Arctic Council also needs to be further promoted.

Thoughts on Current China-U. S. Relations

Aheated debate arose on the nature of China-U. S. relations among scholars inthe two countries. Are the two "strategic partners"? "Competitors"? "Neitherfriends nor enemies"? Or even "Potential enemies"? But largely since 1997, alongwith the establishment of the framework for "a constructive strategic partnership",the definition seems to has been accepted by the mainstream in the Chinese academ-ic circle. By contrast, Governor George. W. Bush, the Republican

Expectations for Future China-U.S. Relations

The heads of state of China and the U.S. reached a consensus in Osaka at the end of June, agreeing to restart trade negotiations on the basis of equality and mutual respect. The U.S. side stated that it would no longer impose new tariffs on Chinese imports, sending a positive sign of the U.S.-China relationship to the international community. On July 3, the Washington Post published an open letter signed by 100 people from the academic, diplomatic, military, and business circles of the U.S. to President Trump and the U.S. Congress, affirming that the consensus is the intention of the two peoples and is in line with the expectations of the international community. The decline in U.S.- China relations is not in line with U.S. and global interests, and China is not an enemy of the U.S., nor does China pose a threat to U.S. national security.

Two-Dimensional Numerical Simulation of the DC Glow Discharge in the Normal Mode and with Einstein’s Relation of Electron Diffusivity

This paper presents an investigation of a DC glow discharge at low pressure in the normal mode and with Einstein＇s relation of electron diffusivity. Two-dimensional distributions in Cartesian geometry are presented in the stationary state, including electric potential, electron and ion densities, longitudinal and transverse electrics fields as well as electron temperature. Our results are compared with those obtained in existing literature. The model used in this work is based on the first three moments of Boltzmann＇s equation. They serve as the continuity equation, the momentum transfer and the energy equations. The set of equations for charged particles presented in monatomic argon gas are coupled in a self-consistent way with Poisson＇s equation. A parametric study varying the cathode voltage, gas pressure, and secondary electron emission coefficient predicts many of the well-known features of DC discharges.

China-US Cybersecurity Dilemma and Its Impacts

The interaction between China and the US over cybersecurity has plunged into mutual opposition,causing a dilemma of cybersecurity cooperation and negatively impacting China-US relations.A more negative attitude of US society to China supports policymakers in their assertive anti-China concept of security.Because this situation will prevail and will further aggravate competition,repositioning China-US cyber relations and maintaining its stability is of great significance for the two sides to avoid conflicts,build trust,and explore limited cyber cooperation.

Russia-India Relations:New Changes and Prospects

Among the major countries in the world,Russia and India are two that have always maintained relatively stable relations.However,recent years have witnessed profound transitions in the regional and global strategic environments,hence increasing divergence between their foreign policy strategies.Furthermore,the traditional drivers of cooperation between the two countries are weakening,such that their disagreements are accumulating in plain sight.Their perceptions and policies surrounding the Indo-Pacific,in particular,have created significant strategic discord.In the foreseeable future,the foundational basis for strategic cooperation between Russia and India will not be fundamentally shaken,but reversing the trend of their drifting foreign policies will prove to be difficult.The gap between the two sides will continue to exist and is likely to further enlarge.The trajectory of Russia-India relations will entail changes in the international and regional landscapes.Overall,a stable Russia-India relationship is in China’s best interest.

China-US Competition in Digital Technologies and EU Strategy

Unable to catch up with China and the United States in the short term,the European Union is in an unfavorable position in the booming digital technology sector needed for economic growth.Within the context of intensifying technological competition and diplomatic strain between China and the US,the EU and European countries have adapted their digital strategies.As a former balance strategy shifts toward constraining Chinese tech companies,Europe’s technological sovereignty is at stake.To enhance European tech capability and control,key measures include increased investment in digital tech,formation of a single European dataspace,and rules based on European values.The interplay between technology and geopolitics and the rising importance of values in digital regulations make possible a technology alliance,despite the introduction of protectionism into the mix.China will need to understand the situation and give positive response.

The Dimensions and Management of China-US Financial Competition

During a period of profound adjustments to the international power structure,China-US financial competition may intensify and lead to a crisis for the international financial system and even the international power system.The China-US financial relationship is structured in mainly four dimensions:the international monetary system,bilateral financial exchanges,the international financial system and the construction of international financial and/or economic concepts.Management of this competition relationship is thereby four-pronged:managing the relationship between the RMB and the US dollar in the international monetary system,the China-US bilateral creditor-debtor relationship,the indirect China-US relationship in global financial governance organizations and normative frameworks,and the divergence of both countries in regard to their economic ideologies.In particular,to stabilize the international monetary system,China should postpone the strategic confrontation between the RMB and the US dollar,strengthening their complementarity and cooperation based on market choice and their monetary function.Meanwhile,China should be prudent as a creditor to the United States,neither coerced by its over-reliance on American financial markets,nor tempted to weaponize the US debt by dumping US bonds.Also,before aiming for systematic reforms,China should first aim to become a stakeholder in the current global financial governance system by comprehensively accepting and becoming deeply integrated into it.Finally,China should avoid the economic competition model between China and the United States,and should instead apply the“Chinese Approach”to better facilitate solutions to international problems.These approaches to crisis management aim to help China endure this turbulent period of the international power system with more prudent strategies and policies,and to maintain a relatively stable international financial and economic environment for the sustained rise of its economy and for the rejuvenation of the Chinese nation.
