Japanese Prime Minister Shigeru Ishiba has arrived in the Philippines to further boost an alliance in the face of China’s growing assertiveness in the region and he plans to symbolically board a Japan-built Philippine patrol ship that has repeatedly clashed with the Chinese coast guard.

Japanese Prime Minister Shigeru Ishiba held talks on Tuesday with President Ferdinand Marcos Jr, in a move to advance security and economic ties between two of Washington's closest Asian allies amid rising Indo-Pacific tensions.

The leaders of Japan and the Philippines pledged in Manila on Tuesday to deepen security ties, including increased intelligence sharing, as they grapple with territorial disputes with China. Japan has its own dispute with China over uninhabited islands in the East China Sea -- known as the Diaoyu in China and Senkaku in Japan -- which are claimed by Beijing but administered by Tokyo.
