Syrian President Bashar al-Assad is planning to visit Kim Jong Un, North Korea’s state media reported Sunday, for what could be the North Korean leader’s first summit meeting with a foreign head of state in his capital, Pyongyang.

The report didn’t specify when a visit by Mr. Assad might take place, but quoted the Syrian president as saying: “I am going to visit the DPRK and meet HE Kim Jong Un,” using the acronym for the North’s formal name, the Democratic People’s Republic of Korea. “HE” is short for “His Excellency.”

If the visit takes place, it will add to a recent burst of diplomacy between North Korea—one of the world’s most isolated countries—and its neighbors and allies.

In recent months, Mr. Kim has met twice with South Korean President Moon Jae-in at the inter-Korean demilitarized zone and twice visited Chinese President Xi Jinping in China. Mr. Kim has also hosted Mike Pompeo, now the U.S. Secretary of State, in North Korea twice in recent months, and on Thursday he welcomed Russian Foreign Minister Sergei Lavrov in Pyongyang.

Mr. Kim is also slated to sit down with President Donald Trump at a summit on June 12 in Singapore.
