His trade war with China is undermining diplomatic efforts to denuclearize North Korea, as well as other US objectives. Trump still seems to think that this trade war is going to lead to an easy win. It's not because of China that North Korea is repeating this pattern and failing to give up their weapons. While US intelligence , as well as reporting from the International Atomic Energy Agency , indicates that North Korea may still be developing its nuclear program, Xi has suggested ending sanctions against North Korea. Trump's acknowledgment that Beijing is not helping us with North Korea is just the beginning of the diplomatic fallout we may see from his trade war.
