- China claims about 90% of the South China Sea, overlapping the exclusive economic zones of five Southeast Asian nations.
- Philippines is bound by the 1951 Mutual Defense Treaty with the US, obligating Washington to aid Manila if Chinese forces attack.
- Xi Jinping reportedly aims to have the capability to invade Taiwan by 2027, intensifying regional security concerns.
- US ships and aircraft regularly patrol the South China Sea, contesting Beijing’s claims and supporting Southeast Asian allies.
Why it matters: The Philippines, facing China's 90% claim and Xi's 2027 invasion target, will lean on its 1951 treaty, driving up US defense spending and risking a costly accidental war that could disrupt global trade.
