China appears to have taken new steps to restrict access to the disputed Scarborough Shoal in the South China Sea, with satellite images showing a floating barrier and multiple vessels at the entrance to the lagoon.
Images obtained by Reuters on April 10 and 11, 2026, reveal four fishing boats anchored near the entrance, a 352-metre floating barrier stretching across it, and at least one Chinese naval or coast guard ship nearby. Philippine officials reported that six Chinese maritime militia vessels were inside the shoal, with three more positioned outside, seemingly blocking entry.
The Scarborough Shoal lies entirely within the Philippines’ exclusive economic zone, but China claims it as its own territory and has controlled it since seizing it in 2012 after a standoff with Philippine vessels.

A Philippine coast guard spokesperson said China installed the barrier on April 10–11. Similar barriers have been placed before and later removed by Philippine forces. This latest one also appears to have been taken down over the weekend, but Philippine Navy patrols continue in the area.
Last year, China declared the shoal a national nature reserve, a move Philippine security officials described as a step toward formal occupation.
The development is being closely watched by diplomats and analysts, who warn that rising tensions at the shoal — one of Asia’s most contested maritime sites — could escalate into armed conflict. The situation is particularly sensitive as the United States is currently preoccupied with the conflict in the Middle East.
Thousands of US and Philippine troops are scheduled to begin large-scale joint military drills across the Philippines this month, including exercises in Zambales province, roughly 120 nautical miles from the shoal.
