The Philippine President, Ferdinand R. Marcos Jr., has said his country will not give up any of its territory to foreign powers, in a speech to the Australian parliament.
Mr Marcos, who is the first Philippine leader to address the parliament, said the Philippines was facing threats to its regional peace and stability, similar to those it faced during World War II.
He said his country had an interest in keeping the South China Sea, a key trade route, free and open, and in respecting the international law of the sea.
He also praised the strategic partnership between the Philippines and Australia, and called for joint efforts to protect the peace they had fought for in the past.
Mr Marcos is on a three-day visit to Australia, where he is expected to discuss trade, security, and cooperation on issues such as climate change and terrorism.
