Japan has sounded out China and South Korea about holding a trilateral summit in late July in Tokyo, diplomatic sources said Tuesday.
The summit between the three countries would be the first since one held in November 2015 in Seoul.
Prime Minister Shinzo Abe hopes to strengthen cooperation with his Chinese and South Korean counterparts to address threats from North Korea's nuclear and ballistic missile programs while accelerating preparations for a visit to China he aims to arrange early next year, the sources said.
