By Kim Jong-un but especially by President is Xi Jinping who has orchestrated the lead-up to the summit and has had continuing meetings with Kim since then. ~ BTW, both South Korea and Japan have been involved with talks with both China and Russia in recent months. It would seem that they are making alternate plans for an Asia without any US influence going forward. ~ So, it seems to me, that we have already given up quite a bit.
