In 2017，the global economy will continue its trend in the second half of 2016 and move forward with low-speed growth. However，a series of events such as trade protectionism and North Korea’s N-bomb tests have added uncertainty to the main theme of the low-speed growth of the global economy，which inevitably affect the economic and trade cooperation in Northeast Asia. In the first three quarters of 2017，China，as the world’s most traded country，has become increasingly influential in terms of regional influence and international influence and has become an indispensable main force in guiding economic and trade cooperation in the Northeast Asia. The lack of raw materials，export-oriented economic structure and geopolitical advantages of regional economic powers of Japan and South Korea have determined the inevitable requirements for developing economic and trade cooperation with the countries in the region. Economic development cannot do without their energy exports of Russia and Mongolia with rich resources in the region，which are complementary in economic and trade cooperation with countries in the region.
