Prime Minister Lee Nak-yon will deliver a letter from President Moon Jae-in when he meets this week with Japanese Prime Minister Shinzo Abe. 

Prime Minister Lee's press secretary confirmed on Tuesday that Moon’s letter will be delivered to Abe during a roughly 10-minute meeting set for Thursday in Tokyo. 

The letter, believed to express Moon’s will to improve Seoul-Tokyo relations, could help ease the long-standing tensions between the two countries. Whether or not Moon presses for a summit with Abe is also drawing attention. 

The prime minister’s office confirmed Moon’s letter was also delivered to Japanese Emperor Naruhito via a diplomatic channel on Tuesday, when his enthronement ceremony was held, but the content was not disclosed.
