The latest revelation has highlighted the realities regarding China’s neglect of its duty to implement sanctions on North Korea, which allowed its nuclear and missile development to proceed. Countries concerned must not sit on their hands, doing nothing about a loophole in efforts to contain North Korea.
China has always advocated compliance with the UN resolution for strict sanctions against North Korea, but its slow action to cut off North Korean coal imports shows that China has clearly not been strictly enforcing the sanctions. As a "responsible major power" China should not be an enabler of North Korea’s militarism. The US, Japan and South Korea should all back Taiwan in its push to lead China to democratization, which will in turn put pressure on North Korea to democratize.
