The People's Liberation Army dispatched vessels and aircraft to the South China Sea over the weekend to monitor joint US-Philippine maritime drills near the disputed Scarborough Shoal.
Beijing stated that the exercises undermined regional stability and vowed to safeguard its territorial sovereignty, marking a direct response to the allied naval presence in the contested zone.
This deployment follows a rare and direct naval stand-off earlier this week, where four Chinese warships confronted a Philippine Navy vessel in the same waters.
The escalation adds to a broader pattern of friction, including recent Chinese accusations against Japanese warplanes and ships for conducting surveillance operations during the deployment of the Liaoning aircraft carrier group to the western Pacific.
For markets, the heightened military activity reinforces the shipping disruption risk that has already begun to impact freight rates and energy logistics.
Adnoc L&S recently raised its profit outlook citing shipping disruptions, while Navios Maritime bonds have traded above par as credit demand holds firm amid the uncertainty.
