Japanese Prime Minister Shinzo Abe and a special envoy of new South Korean President Moon Jae In agreed Thursday to resume "shuttle diplomacy" between the two leaders, according to the envoy. The shuttle diplomacy, which sees the leaders visit each other's countries roughly every year, has been suspended since December 2011 under the administration of then President Lee Myung Bak.The two leaders could hold their first face-to-face talks in July on the margins of a summit of Group of 20 major economies in Germany.

[...] “the JET Programme has been wildly successful as a public diplomacy effort for Japan.” Calling it a “vital diplomatic tool."
