The opportunity to unravel the threads of the ROK-US relationship is drawing attention next month with the UN General Assembly and the announcement of US investment. President Yoon Suk Yeol and US President Donald Trump may meet at the UN General Assembly to discuss North Korea policy coordination and the possibility of resuming North American dialogue. In particular, South Korea's announcement of US investment is expected to play an important catalytic role in improving ROK-US relations. It is also noteworthy whether North Korea will dispatch a heavyweight figure to the UN General Assembly. This could suggest the possibility of resuming North American dialogue. South Korea should continue close communication with the United States to alleviate concerns about 'Korea Passing' and persist in its efforts for North Korean denuclearization.
