HANOI, Vietnam (AP) — North Korea’s foreign minister is holding talks in Vietnam in a visit to a fellow communist country as part of efforts to break the North’s diplomatic isolation.

Ri Su Yong arrived Tuesday night for a four-day visit before traveling on to Myanmar for an ASEAN Regional Forum meeting, which will also be attended by U.S. Secretary of State John Kerry and foreign ministers from Japan, South Korea and China on Sunday.

Ri held talks with his Vietnamese counterpart Pham Binh Minh and will also meet President Truong Tan Sang.

Unlike Vietnam, which launched reforms in the mid-1980s opening up to foreign trade and investment, North Korea remains one of the world’s most isolated countries over its nuclear weapon program.
