Britain says its relations with countries in the Indo-Pacific region are "a permanent pillar" of the country's international policy.
The country wants to step up its engagement in the region. This comes amid the backdrop of China's increasing assertiveness.
The British government on Monday released a review of its foreign and security policies.
The report says that "China under the Chinese Communist Party poses an epoch-defining and systemic challenge with implications for almost every area of government policy and the everyday lives of British people."
It says Britain will defend its security in close cooperation with its allies and partners.
In 2021, Britain deployed its state-of-the-art aircraft carrier, the HMS Queen Elizabeth, in the Indo-Pacific region.
The HMS Queen Elizabeth's aircraft carrier unit held a joint exercise with Japan's Self-Defense Forces.
Britain and France agreed at a regular summit meeting in March to maintain their presence in the Indo-Pacific region by working together to send joint forces and aircraft carriers to the region.
The report also focused on the "AUKUS" partnership. AUKUS is the trilateral framework that Britain, the United States and Australia are a part of. The report says the AUKUS partnership will help strengthen ties with Australia, which is one of Britain's closest partners.
Britain is expected to provide Australia with nuclear-powered submarines.
The two countries plan to jointly develop technology in various fields, such as quantum science, artificial intelligence and electronic warfare.
Britain has been trying to strengthen relations with non-EU member countries since before it left the bloc in 2020. This is part of its "Global Britain" policy.
