TOKYO: Japan and the United States are discussing ways to boost military cooperation, Tokyo's top government spokesman said on Monday, after reports said US operations in the East Asian country could be strengthened to counter China.
Japanese media and the Financial Times newspaper, citing diplomatic sources, said a review of the allies' security pact would be announced at a US-Japan summit in Washington, D.C. next month.
The reports said the move was part of steps to counter Beijing's expanding military and political influence in the Asia-Pacific region.
"Japan and the United States have been discussing ways to strengthen cooperation in command and control in order to enhance interoperability and readiness," government spokesman Yoshimasa Hayashi told reporters.
"My understanding is that nothing has been decided regarding the American side's structure, including strengthening the functions of US Forces Japan," he said.
There are 54,000 US military personnel based in Japan, a key ally of Washington.
Tokyo is ramping up defense spending to the North Atlantic Treaty Organization standard of 2 percent of gross domestic product by 2027, and has warned that Beijing poses the "greatest strategic challenge" to its security.
Japan's Yomiuri daily, citing US and Japanese sources, reported about the potential changes on Monday.
A permanent US-Japan joint team could be set up in Japan to ensure closer military coordination, the newspaper said, explaining that currently, Japan has to deal with the Hawaii-based US Indo-Pacific Command for various decisions.
The Financial Times said "the Pentagon is some way from making any decision," but that both Japan and the US were keen to boost ties "to respond to what they view as a growing threat from China."
It also described the plans as "the biggest upgrade to [the US-Japan] security alliance since they signed a mutual defense treaty in 1960."
Japanese Prime Minister Fumio Kishida will meet US President Joe Biden on a state visit to Washington on April 10.
Kishida is also due to take part in Japan's first three-way summit with the US and the Philippines the following day.
