The research questions why these three countries have some similar characteristics in their diplomacies and foreign policies, which differentiates them both from traditional developed countries and typical developing countries. Before the assessment of this question, analysis of culture and its characteristics, international strategies and diplomacies of these three BRICS countries is necessary and appropriate. Culture plays a special and crucial role in international politics or international relations. The unique cultures of Eurasian BRICS countries, China, Russia and India, have special influences on their diplomacies, which has created a new landscape in current world economy and politics.展开更多

The Abe administration has long pursued a "bet-hedging" strategy towards China. Although it claims that it attaches great importance to the ties between Japan and China, it pursues "Strategic Diplomacy" and "Value-oriented Diplomacy" to hype up the so-called "China Threat" in international community. It not only makes China-Japan relations to continuously fall into a vicious circle of"repeated deterioration", but also become an uncertainty for peace and stability in East Asia and the regional security. In addition, it reflects the "diplomacy dilemma" of the Abe administration's China policy.展开更多

Starting from the promotion of bilateral interaction by means of the China-Japan Ruling Party Exchange Mechanism to discussing the feasibility of China-Japan economic and trade cooperation under the Belt and Road Initiative(BRI), and influenced by US trade protectionism in particular, the Abe administration decided to implement foreign policy that would ease tensions between China and Japan,claiming that China-Japan relations"has entered the era of coordination from that of competition."The adjustment of the Abe administration's China policy is still tactical, and it remains uncertain whether Japan can adhere to the spirit of the four political documents signed between China and Japan and implement the four-point principled agreement they reached.展开更多

The most important reason is that political climate is still not very conducive to carrying out large-scale interactions. With time passing by,India and China find that mutual interactions and cooperation are more and more important,and academic interaction is most effective,meaningful and enduring way of bringing the two close.There are limitations that should arouse our attention in order to deal with them. The most important problem is'security consideration',which hinders free academic interaction. The second one is'limited resources',and both countries are lacking of funds and financial support.

The overallseroprevalence rate of H. pylori infection is 44.2% in China, 37.6%-43.2% in Japan,and 51.0% in South Korea. H. pylori can cause peptic ulcer disease and gastriccancer. East Asian countries have high rates of gastric cancer (age-standardizedincidence rate: 20-30 per 100000). The Kyoto global consensus report emphasizedthat H. pylori gastritis should be considered the main cause for the development ofgastric cancer. H. pylori treatment guidelines in China, Japan, and South Koreahave recently been revised according to data from each of those countries.However, emerging antibiotic resistance is an important barrier to H. pylorieradication. The recommended H. pylori treatment regimens differ among thosethree East Asian countries. In this review, recent guidelines and up-to-dateresearch on H. pylori treatment regimens from China, Japan, and South Korea arediscussed.展开更多

It shows from the analysis and comparison that the floristic relation of East China with Japan is closer than that with northeast China and Korea. The similarity indices of genera and species of seed plants in the two regions are very high, being 72.6% and 43.3% respectively. The structure and species composition of broad-leaval evergreen forests in the two regions are also similar, and there exist many corresponding communities, such as the forests of Castanopsis carlesii and C. sieboldii. Many plants in East China are conspecific with there in Japan, such as Cercidiphyllum japonicum, Magnolia sieboldii, Nandina domestica etc. Though the genera of Ginkgo, Liriodendron, Sassafras etc. existing now in China are extinct from Japan, their fossils have been discovered from the Tertiary strata in Japan. It seems to indicate that the phytogeographical affinities between East China and Japan are closer in ancient the than it is now, and both of the forest floras originated from the same flora. The flora in Japan did not evolve independently until it separated from Chinese continent and drifted northeastwards in the late period of the Tertiary.展开更多

It seems that an alternation of signs of“+, -, +” exists in the geographical pattern of the correlation in summer rainfall from North China to India through the Tibetan Plateau. However, it appears that the teleconnection of summer rainfall variations between North China and India is unstable. Over 1945 - 1974, the correlation coefficient (hereafter as CC) is as large as 0.7. In contrast, the CC is about -0.3 over 1827-1856. Further studies, based on observations starting from 1813, showed that the correlation is strong when summer rainfalls in both North China and India are large, and vice versa. In order to find what induce the change of the teleconnection, variations of summer rainfall in both North China and India, mean sea surface temperature (SST) in the eastern equatorial Pacific and the frequency of ENSO events were examined in relation to the change of the teleconnection. The result showed that the teleconnection appears weak when the mean SST is high and the frequency ofLa Nifia events is low; the teleconnection is strong when the mean SST is low and the frequency ofLa Nina events is high. At last, it is notable that La Nifia happens in only 3 years during the recent 30 years from 1976 to 2005 and the teleconnection becomes weak too.展开更多

By analyzing these images, we found that the gravity in Liaodong peninsula area showed an obvious increase of 80 × 10^-8ms^-2 during about one- and-half year before the 2011 Japan Mwg. 0 earthquake, and a rapid decrease after the earthquake. This gravity variation is similar to that observed previously for the 1976 Tangshan 1147.8 earthquake.展开更多

The monthly-mean rainfall data observed at 160 stations in China, monthly-mean sea surface temperature(SST) of the Hadley Center for Climate Prediction and Research and monthly-mean air temperature from the NCEP reanalysis during 1960–2011 were used. Correlation analysis indicates that the SSTAs in the Japan Sea in September may last for three or four months and are an important index for forecasting the winter rainfall and air temperature in NE China. Positive SSTAs in the central Japan Sea and in the sea area east of Tokyo correspond to positive rainfall anomaly and negative air temperature anomaly in NE China. With the rise of SST in the Japan Sea, a weak cyclone appears over the Japan Sea. The northeasterly wind transports water vapor from the Okhotsk to NE China, resulting in more rainfall and lower air temperature. Negative SSTA years are accompanied by warmer air temperature and less snow in NE China. The 1000 h Pa geopotential height anomaly and wind anomaly fields are simulated by IAP-9L model, which supports the analysis results.展开更多

This paper discusses the role of China and India as important global actors in light of development imperatives in the two countries.The article then looks at emerging approaches in the two countries related to financing, science, technology & innovation policy, and subnational actions. The objective is to review efforts in China and India for contributing to learning experiences for other countries. The final section discussed the ways forward in terms of examining the role of China and India in terms of national policy strengthening as well as in global agenda setting. Implementation of sub-national initiatives in both countries faces challenges due to lack of adequate financing as well as knowledge such as greenhouse gas inventories and disaggregated resource and socio-economic assessments. Both India and China are making efforts in technology and innovation domains to set foot on a trajectory of low carbon development with varying degrees of success. In finance,both China and India have experimented with various instruments-the key difference is that China has taken the support of regulation more while India has leaned on to market based instruments. Both China and India are moving on an encouraging track regarding low carbon development with fairly well-designed domestic policies and consistent international engagement.展开更多

In accordance with results of a literature search, review of information disclosed online, and questionnaire survey conducted, the findings of this study are summarized in the following two points: (1) The results show that in Japan most of the home appliances mentioned above have been collected through home appliance recycling tickets, resulting in an issue of "requiring some effort" in treatment and recycling stages, and most plants have contracted out their e-waste recycling; (2) It is found out that advantages of the recycling system in Japan include easiness to monitor concrete data and thorough environmental friendliness ensured while its disadvantages include illegal dumping and export. It becomes apparent that advantages of the recycling system in China include a high reuse rate, low treatment cost, and fewer illegal dumping while its disadvantages include less safe reused products, environmental pollution caused by e-waste treatment, illegal import and difficulty in obtaining data.展开更多

However, after Trump took office as president of the United States (US), the US withdrew from the Paris Agreement. As the biggest economy, this would have impacts on the emission space of other countries. This paper, by using the integrated model of energy, environ- ment and economy/computable general equilibrium (IMED/CGE) model, assesses the impacts of the US withdrawal from Paris Agreement on China, India in terms of carbon emission space and mitigation cost under Nationally Determined Contributions (NDCs) and 2~C scenarios due to changed emission pathway of the US. The results show that, under the condition of constant global cumulative carbon emissions and fixed burden sharing scheme among the countries, the failure of the US to honor its NDC commitment will increase its carbon emission space and decrease its mitigation cost. However, the carbon emission space of other regions, including China and India, will be reduced and their mitigation costs will be raised. In 2030, under the 2℃ target, the carbon price will increase by US$14.3 to US$45.3/t in China and by US S10.7 to US$33.9/t in India. In addition, China and India will incur additional GDP loss. Under the 2℃ target, the GDP loss of China would increase by US$23.3 to US$72.6 billion (equivalent to US$17.4 to US$54.2/capita), and that of India would rise by US$14.2 to US$43.1 billion (equivalent to US$9.3 to US$28.2/capita).展开更多

文摘This study aims to identify processes, current situations and issues of recycling systems for four home appliances, namely, air conditioners, television receivers, refrigerators, and washing machines, among e-wastes in China and Japan for understanding and comparison of their characteristics. In accordance with results of a literature search, review of information disclosed online, and questionnaire survey conducted, the findings of this study are summarized in the following two points: (1) The results show that in Japan most of the home appliances mentioned above have been collected through home appliance recycling tickets, resulting in an issue of "requiring some effort" in treatment and recycling stages, and most plants have contracted out their e-waste recycling; (2) It is found out that advantages of the recycling system in Japan include easiness to monitor concrete data and thorough environmental friendliness ensured while its disadvantages include illegal dumping and export. It becomes apparent that advantages of the recycling system in China include a high reuse rate, low treatment cost, and fewer illegal dumping while its disadvantages include less safe reused products, environmental pollution caused by e-waste treatment, illegal import and difficulty in obtaining data.
文摘Climate mitigation has become a global issue and most countries have promised their greenhouse gas reduction target. However, after Trump took office as president of the United States (US), the US withdrew from the Paris Agreement. As the biggest economy, this would have impacts on the emission space of other countries. This paper, by using the integrated model of energy, environ- ment and economy/computable general equilibrium (IMED/CGE) model, assesses the impacts of the US withdrawal from Paris Agreement on China, India in terms of carbon emission space and mitigation cost under Nationally Determined Contributions (NDCs) and 2~C scenarios due to changed emission pathway of the US. The results show that, under the condition of constant global cumulative carbon emissions and fixed burden sharing scheme among the countries, the failure of the US to honor its NDC commitment will increase its carbon emission space and decrease its mitigation cost. However, the carbon emission space of other regions, including China and India, will be reduced and their mitigation costs will be raised. In 2030, under the 2℃ target, the carbon price will increase by US$14.3 to US$45.3/t in China and by US S10.7 to US$33.9/t in India. In addition, China and India will incur additional GDP loss. Under the 2℃ target, the GDP loss of China would increase by US$23.3 to US$72.6 billion (equivalent to US$17.4 to US$54.2/capita), and that of India would rise by US$14.2 to US$43.1 billion (equivalent to US$9.3 to US$28.2/capita).
文摘This essay attempts to explore the current cultural diversity in China and India with the comparison of policy responses,especially the multiculturalism and language policies,as well as the policies on the workplace.Results show that India enrichedand deepened its multiculturalism through the recognition of languages diversity,while China weakened its cultural diversity bypopularizing one official language,Mandarin.However,both China and India should do more in practice to make different ethnicgroups live and participant as equal partners in the social life.
