Beijing accuses Philippines of deliberately slamming its vessel in South China Sea

China is rapidly expanding its military and has become increasingly assertive in pursuing its claim to virtually the entire South China Sea which is crucial to international trade

China accused a Philippines coast guard ship of deliberately colliding with a Chinese vessel on Saturday in the latest flareup of tensions over disputed waters and maritime features in the South China Sea.

In a statement posted on social media, Chinese coastguard spokesperson Liu Dejun said that the Philippine ship, with hull number 9701, collided with the Chinese ship, 5205, just after 12.06pm (04.06GMT) Saturday.

As the Philippine ship maneuvered, it “deliberately collided” with the Chinese coastguard ship “in an unprofessional and dangerous manner, resulting in a collision”, Mr Liu said, adding the standard claim that the Chinese ship was operating within regulations, without giving any details.

China is rapidly expanding its military and has become increasingly assertive in pursuing its claim to virtually the entire South China Sea which is crucial to international trade. The tensions have led to more frequent confrontations, primarily with the Philippines, whose security the US is treaty-bound to ensure. The longtime territorial disputes also involve other claimants including Vietnam, Taiwan, Malaysia and Brunei.

China has rejected a ruling by a UN-backed arbitration panel that negated almost all of Beijing's historically-based claims in the South China Sea.

On Tuesday, the head of US Indo-Pacific Command said the US military is open to consultations about escorting Philippine ships in the disputed waters amid the spike in hostilities. Adm. Samuel Paparo’s remarks provided a glimpse of the mindset of one of the highest American military commanders outside the US mainland on a prospective operation that would risk putting US Navy ships in direct collisions with those of China.

Chinese coast guard, navy and suspected militia ships regularly clash with Philippine vessels during attempts to resupply Filipino sailors stationed in parts of the South China Sea claimed by both countries. As these clashes grow increasingly hostile, resulting in injuries to Filipino sailors and damage to their ships, the Philippine government has faced questions about invoking the treaty alliance with Washington.

The latest incident came days after Chinese and Philippine coastguard ships collided near Sabina Shoal, a disputed atoll. At least two vessels were reported to be damaged in Monday’s collision but there were no reports of injuries.

Sabina Shoal lies about 140km (85miles) west of the Philippine province of Palawan, in the internationally recognized exclusive economic zone of the Philippines.

The atoll is near Second Thomas Shoal, another flashpoint where China has hampered the resupply of Philippine forces. Both countries reached an agreement last month to prevent further confrontations at the shoal.

Also Saturday, Japan lodged a formal protest via China’s embassy against what it called an incursion by a Chinese survey ship into its territorial waters, the latest incident fueling unease among Japanese defense officials, already concerned about the growing military cooperation between the Chinese and Russian air forces.

On Monday, Tokyo also protested a Chinese military aircraft briefly entering Japan’s southwestern airspace. Chinese foreign ministry spokesperson Lin Jian said on Tuesday his country had “no intention” to violate any country’s airspace.
