英文摘要 |
The Policy of the Donald Trump administration on North Korea was to exert maximum pressure, and economic sanctions were a part of this pressure. Washington considered China as one source of North Korea's missiles and nuclear weapons technology, and the most important trade partner of North Korea. At the same time, China is a permanent member of the UN Security Council. Washington hoped Beijing would use its influence to stop North Korea from developing missiles and nuclear weapons. American policy included implementing UN Security Council resolutions and strengthening economic sanctions. In addition, Washington also sanctioned Chinese companies to block North Korea's access to related technologies and equipments. With China's passive support, the US sanctions on North Korea had some effects. Trade between China and North Korea decreased. Beijing had also tightened controls on missiles and nuclear equipments to prevent North Korea from acquiring related technologies from China. |
