习创会后，创普透露出的一个细节耐人寻味，即习近平给他详细讲解了中朝之间的历史，和中国在朝鲜的立场。用创普的原话，
"After listening for 10 minutes, I realised it's not so easy," Mr Trump said.
"I felt pretty strongly that they had a tremendous power over North Korea. But it's not what you would think."
习创会上，虽然出现美军攻击叙利亚的杂音，但朝鲜问题显然是一个核心议题。从会后创普团队在朝鲜问题上言论上“发乎情”，但行动上“止乎礼”来看，习近平的话他们还是听进去了。
