North Korean Foreign Minister Choe Son-hui met with Vietnamese counterpart Le Hoai Trung in Pyongyang on May 13, agreeing to expand bilateral exchanges and strengthen coordination between the two countries' foreign policy bodies. Trung travelled to North Korea as a special envoy of Vietnamese President To Lam, building on a summit held between Kim Jong-un and Lam in October last year. The visit signals a warming of ties between the two socialist states, with both sides also reaffirming party-to-party cooperation at a separate meeting with a senior Workers' Party official.
