Japan has sent two more used boats that will be refurbished into patrol boats to Vietnam as part of a 500 million yen (US$4.1 million) aid program.
The two 600-ton fishing boats were delivered during a ceremony in the central city of Da Nang on Tuesday, Japanese media reported.
Last year, Japan announced its plan to provide Vietnam with six patrol vessels as part of the 500 million yen official development assistance package for Vietnam. Two were delivered last February and August.
The remaining two are to be delivered by the end of this year.
Japanese Prime Minister Shinzo Abe also mentioned a plan to provide additional used ships during a meeting with Communist Party General Secretary Nguyen Phu Trong in Tokyo in September.
