China's biggest North Korea taboo: discussing life after Kim
Beijing fears that airing the topic will alarm its volatile neighbour, but rising tensions mean it may have to confront difficult questions soon

In discussions between the US and China about reining in North Korea, one topic remains taboo: What would happen if Kim Jong-un’s regime collapses?
For years, China has rebuffed US attempts to raise the topic at so-called Track 2 dialogue sessions between academics in each country’s foreign policy establishment, according to Bonnie Glaser, senior adviser for Asia at the Centre for Strategic & International Studies (CSIS) in Washington, who has led the US side in such talks.
Attendees included people from Chinese government-affiliated research institutions and military officers, she said.
From China’s perspective, officially broaching the issue could alarm its neighbour, which has received Beijing’s backing since the Korean war in the 1950s.
There’s also a fear that it would give the US an advantage in one day reunifying the Korean peninsula on its terms.
