China is worried about the outcome of the Trump-Kim Singapore summit as a stabilizing relationship between the US and North Korea would mean less regional power for China. Despite enforcing UN sanctions, China remains North Korea's closest trading partner and traditional friend. Beijing fears that negotiations could fail spectacularly, leading to military confrontation on China's doorsteps. However, there is concern that Beijing does not have as much control over North Korea as the US believes, making it challenging for China to influence outcomes. Verification is crucial to any agreement made at the summit, and it is unlikely that North Korea will agree to allow inspectors in its most secretive labs.
