US President Barak Obama will discuss the issue with Prime Minister Shinzo Abe during his visit to Japan next week. A deal is expected to be included in the joint statement signed by both leaders and issued after the summit meeting, the Yomiuri Shimbun reported.
Under the planned accord, the two countries are expected to offer patrol vessels to members of the Association of Southeast Asia Nations (ASEAN), the mass-circulation daily said, citing unnamed sources.
The Japan-US initiative is aimed at helping ASEAN members not only take effective measures against pirates and natural disasters but also boost their deterrence capacity against China's assertive claim to disputed territories, it added.
"Improving ASEAN's ocean surveillance capability will benefit Japan and the United States," a Japanese government official said, according to Yomiuri.
China and Japan are at loggerheads over the ownership of a string of islands in the East China Sea, while Beijing is also in dispute with several nations over territory in the South China Sea, which it claims almost in its entirety.
