Hanoi meeting can initiate positive changes

Editor's note: US President Donald Trump and Kim Jong-un, top leader of the Democratic People's Republic of Korea, are scheduled to meet in Hanoi, Vietnam, on Wednesday and Thursday. Columnist Niutanqin comments in his WeChat post:

Despite the rapport forged between the two leaders at their first meeting in Singapore last year, many concrete problems have been left unsolved, if not untouched. So there must be some concrete outcomes from their second meeting.

As Kim visited Beijing and Sergey Lavrov, Russian foreign minister, called on Hanoi not long ago, the meeting is related to almost all stakeholders in the region. Whatever the outcome will be, the summit will influence the situation in East Asia in the period that follows.
