Opinion | South China Sea: US, Chinese commitments to avoid open conflict are about to be tested
- Leaders of the Philippines, US and Japan will meet this week in Washington for unprecedented summit
- Hostilities have intensified over contested Second Thomas Shoal as worries grow over potential flashpoint with China

US-China ties are about to sail into choppy waters as military tensions in the South China Sea approach a boiling point.
Aside from plans to grant the United States access to more Philippine military bases – some strategically located near Taiwan – Manila on Sunday conducted joint exercises with the US, Japan and Australia near the contested waters.
Beijing has also geared up for a possible conflict, organising several recent live-fire naval drills and on Sunday “joint naval and air combat patrols”, while accusing Manila of provocations and playing “the victimised underdog” in a bid for international sympathy.
Tensions will heat up further this week as Marcos is expected to unveil plans at a summit in Washington on Thursday with US President Joe Biden and Japanese Prime Minister Fumio Kishida to launch joint naval patrols in the South China Sea.
US seputy secretary of state Kurt Campbell last week compared the trilateral gathering to the landmark Camp David summit last year among the leaders of the US, Japan and South Korea, cementing their de facto military alliance.
