President Trump will hold a two-day summit February 27-28 with North Korean leader Kim Jong Un in Vietnam to continue efforts to persuade Kim to give up his nuclear weapons.

President Trump said his outreach to Kim and their first meeting in June in Singapore opened a path to peace. However, there is not yet a firm plan that says how denuclearization could be implemented.  Denuchlearizing North Korea is something that has eluded the U.S. for more than two decades.

“We continue our histroic push for peace on the Korean Peninsula,” President Trump said on Tuesday in his State of the Union address.

Satellite video taken since the June Summit has indicated North Korea is continuing to produce nuclear materials.  At the second summit, some observers say North Korea may seek to trade the destruction of its main nuclear complex for a U.S. promise to formally declare the end of the 1950-53 Korean War.

On a related issued, the State Department said this week that the United States and South Korea have reached a tentative agreement to share the costs of keeping 28,500 U.S. troops there.
