U.S. President Donald Trump and North Korean leader Kim Jong Un will hold their second summit on Feb. 27 and 28, this time in Vietnam, Trump said during his State of the Union speech Tuesday — making for a highly symbolic choice that experts say offers something for both sides as they seek to kick-start deadlocked denuclearization talks.

In the annual speech before both houses of the Congress, Trump praised his own efforts to address the North Korean nuclear threat, touting his "bold new diplomacy" — under which Pyongyang has halted nuclear and missile tests for some 15 months — and vowed to "continue our historic push for peace on the Korean Peninsula."

Trump did not immediately reveal where in Vietnam the talks will be held, but Hanoi, the nation's capital, and Danang, a coastal resort town, have both been floated as possibilities.
