It was in China's interest to make its "best efforts" to induce North Korea to denuclearise, he said. North Korea's tests overshadowed multiple gatherings this month of international leaders, including the Group of 20 conference in Bali, where Yoon pressed Chinese President Xi Jinping to do more to rein in North Korea's nuclear and missile provocations. China is South Korea's largest trading partner, as well as a close partner of North Korea. South Korea, Japan, and the United States have agreed to share real time information for tracking North Korean ballistic missile tests. Now Japan faced more and more threats from North Korea’s missile programme, including tests that overfly Japanese islands, Yoon said.
