TOKYO, Jan 6 (Reuters) - The United States and Japan will sign a new research and development agreement to make it easier to collaborate on countering new defence threats, including hypersonics and space-based capabilities, US Secretary of State Antony Blinken said on Thursday (Jan 6).

Foreign and defence ministers of the United States and Japan met virtually to discuss stepping up security ties amid a focus on Japan's role as tensions rise over Taiwan and North Korean missile threats continue.

US Defense Secretary Lloyd Austin said that the meeting would help lay down a framework for the future of the security alliance, including evolving missions to "reflect Japan's growing ability to contribute to regional peace and stability".

Blinken said it was "more critical and also more vital than ever" to keep strengthening and modernising the long-standing US-Japan alliance, citing increased threats from Russia, China and North Korea.

"We're launching a new research and development agreement that will make it easier for our scientists, for our engineers and program managers to collaborate on emerging defence related issues, from countering hypersonic threats to advancing space based capabilities," he said at the opening of the meeting.

North Korea fired a "hypersonic missile" this week that successfully hit a target, its state news agency said earlier.

The two nations would also sign a new five-year agreement covering the continued basing of US troops in Japan that would invest greater resources to deepen military readiness and interoperability, Blinken said.

Japan has agreed with the United States to pay US$9.3 billion to share the upkeep of US forces stationed in Japan over five years from next April.
