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 Philippines' foreign ministry summoned the Chinese ambassador on Wednesday, November 13, to protest against Beijing's establishment of baseline coordinates around the disputed Scarborough Shoal in the South China Sea,

China declared its maritime baselines around Scarborough Shoal after the Philippines passed laws defining its maritime zones and sea lanes last week.

The Philippines has protested China’s baselines around the disputed Scarborough Shoal, as tensions between the two nations build up anew over their competing claims in the South China Sea.
