BEIJING (AP) — China has published baselines for a contested shoal in the South China Sea it had seized from the Philippines, a move that’s likely to increase tensions over overlapping territorial claims.

The move from Beijing comes just a day after the Philippines signed two laws defining the country’s maritime zones

China firmly opposes the Philippines' Maritime Zones Act, which it says "severely infringes on" the its territorial sovereignty and maritime rights in the South China Sea, the Chinese foreign ministry said on Sunday in a statement.
