Japan plans to donate patrol boats costing US$11 million each to the Philippines, ramping up regional efforts to monitor China’s maritime activity in disputed waters, a newspaper said on Monday.

The Japanese government plans to finance the deal in its fiscal this year budget starting in April and hopes to officially sign it early next year, the Nikkei business daily reported.

Japan will then provide the Philippines with the newly built patrol vessels, which will cost more than 1 billion yen each, the newspaper said, without specifying the number of boats on offer.Both countries are locked in separate territorial disputes with China.Japan’s dispute is over a group of uninhabited islands in the East China Sea known as the Senkakus in Japan and the Diaoyus in China.

The Philippines is one of several Southeast Asian countries, including Vietnam, that are in rows with China over claims to parts of the South China Sea. Two of the hotspots are the Spratly Islands and Scarborough Shoal.

The Japanese coastguard also plans to train Philippine and Vietnamese personnel as part of additional efforts to boost security co-operation with Southeast Asia, the Nikkei said.

In the fiscal 2013 budget draft, 2.5 billion yen has been allotted for such expenditure, it said.

Last month, Japanese Foreign Minister Fumio Kishida visited Manila and called for stronger ties with the Philippines to help ensure regional peace.

Japan’s coastguard last month said it would create a special unit comprising 10 new large patrol boats to boost its surveillance of the Senkaku/Diaoyu islands.

The long-running row over the islands intensified in September when Tokyo nationalised part of the chain, triggering fury in Beijing and huge anti-Japan demonstrations across China.

In the most serious high-seas incident yet, Japan last week said that a Chinese frigate locked its weapon-targeting radar on a Japanese navy vessel on January 30. China has angrily denied the charge.
