Trump to China: Keep Tight North Korea Border

President Donald Trump on Monday pressed China to maintain a secure border with North Korea, weighing in ahead of an anticipated June meeting with North Korea's leader aimed at denuclearization while at the same time efforting a trade deal with Beijing.

"China must continue to be strong & tight on the Border of North Korea until a deal is made. The word is that recently the Border has become much more porous and more has been filtering in. I want this to happen, and North Korea to be VERY successful, but only after signing!" Trump tweeted.
