Japanese Defence Minister Minoru Kihara and Foreign Minister Yoko Kamikawa will discuss "bilateral and defence and security issues affecting the region" at the July 8 meeting in Manila, a Philippine foreign affairs department statement said.

The talks follow escalating confrontations at sea between Chinese and Philippine ships as Beijing steps up efforts to push its claims to nearly all of the South China Sea.

Tokyo and Beijing are also at loggerheads over Japan-controlled disputed islands in the East China Sea.

Japan, which occupied the Philippines during World War II, is negotiating a Reciprocal Access Agreement (RAA) with Manila that would allow the countries to deploy troops on each other's territory.

Ex-defence minister Itsunori Onodera, now a ruling-party member of the Japanese parliament, said Friday he hoped negotiations on the defence pact would "make rapid progress" at next month's meeting.

"We recognise the need to further deepen security and defence cooperation between our two countries," Onodera told a press conference on the last day of a five-day visit to Manila.

Onodera said he had met with National Security Adviser Eduardo Ano, Defence Minister Gilberto Teodoro and Foreign Secretary Enrique Manalo to reiterate Japan's commitment to a strategic defence partnership with the Philippines.

"Japan is committed, ready to provide necessary assets to Philippines to protect Philippine security," said Yoshiaki Wada, another member of Onodera's parliamentary delegation.

Tokyo has been building the newest and largest ships of the Philippine Coast Guard, a key element of Manila's efforts to assert its sovereignty in the South China Sea.

Onodera said Japan was "very concerned" by China's behaviour during the latest confrontation between Manila and Beijing off the Second Thomas Shoal.

A Filipino sailor lost a thumb on June 17 when Chinese coast guard members wielding knives, sticks and an axe foiled a Philippine Navy attempt to resupply a garrison on a derelict warship deliberately grounded on the shoal to assert Manila's claim there.

"We oppose any attempt to unilaterally change the status quo by force, or any action that will escalate tension," Onodera said.

Tokyo's Maritime Self-Defence Force held joint naval and air drills with the United States, Australia and the Philippines in the South China Sea in April.

The drills aimed to demonstrate what the participants said was their "collective commitment to strengthen regional and international cooperation in support of a free and open Indo-Pacific".
