Also discussed here are the patterns that the foreign oil companies used in acquiring Russian petroleum assets, and the cooperation models of petroleum exploration and production in Russia. The Russian government encourages foreign oil companies to establish strategic alliances with domestic companies that keep good relations with the government. To achieve this goal, the government provides foreign companies with the space for cooperation in such aspects as advanced technology and management culture. International cooperation in petroleum industry will be further developed under the macro-control of the Russia State energy strategy. The energy cooperation between China and Russia will enter a new phase full of hopes and challenges after the past unfavorable situation is gradually overcome.展开更多

To this end, the causal relationship between the two variables was examined using panel data and Granger standard causality test. The results demonstrate a unidirectional causality from GDP to the number of tourists coming to the ECO countries, it is also concluded that a rise in the country's GDP provides necessary conditions for investment on all sectors of the economy including the tourism sector. In such conditions, if the country's economic priorities comprise tourism development, then tourists will start visiting the country and the industry will flourish. Thus, policy-makers should focus on the increasing GDP if they want to increase the tourists' influx.展开更多

However, compared with the world's leading oil refining powers, the oil refining industry in China still lags behind in terms of overall competitiveness. There is an urgent need to enhance its competitiveness and adjust its product structure, plant structure and capacity structure to both launch a new round of industrial upgrading and coordinate with the associated industries. Great potential exists for China to cooperate with the countries along the Belt and Road initiative in various fields such as petroleum resources, product markets and technical equipment. Together, multi-dimensional cooperation bonded by resources, markets, technologies and capital/funds can be carried out, and cooperation between the upstream and downstream industries throughout the industry chain can be facilitated. There is much to expect from the prospects for cooperative development.展开更多

They emphasize that the Great Divergence between the East and the West began in very late 1800s. However, the emergence of steam engine, the symbol of the Industrial Revolution, is based on the technology accumulation and inheritance of machine tool industry in 16th century Western Europe. In contrast, China in the Ming Dynasty did not have similar machine tool technologies and even when such Western technologies were introduced to China in the late Ming Dynasty-along with clocks and firearms - they were not successfully grafted into Chinese technology tradition. Therefore, China lacked both the key technologies required for an Industrial Revolution and the capability to develop related technologies. The Great Divergence between the East and the West started in the 16th century and the West's technological capability in the heavy industry is the very advantage that brought it ahead of China.展开更多
