PLAN plays silly buggers at sea

The Chinese navy (formally called the People’s Liberation Army Navy) appears to be stepping up their program of harassment:

The incident happened on Sunday as the USNS Impeccable was on routine operations in international waters 75 miles (120km) south of Hainan island, a US statement said.

The ships had "aggressively manoeuvred" around the Impeccable "in an apparent co-ordinated effort to harass the US ocean surveillance ship while it was conducting routine operations in international waters", according to the Pentagon.

When the Impeccable radioed requesting a safe path to leave the area, two Chinese vessels dropped pieces of wood in its path, forcing the US ship to make an emergency stop, the Pentagon said.

"The unprofessional manoeuvres by Chinese vessels violated the requirement under international law to operate with due regard for the rights and safety of other lawful users of the ocean," said Pentagon spokesman Marine Maj Stewart Upton.

Whole thing here.

Update: Longer CNN version of the incident here.

The 281.5-foot Impeccable is one of six surveillance ships that perform military survey operations, according to the Navy. It is an oceanographic ship that gathers underwater acoustic data, using sonar.

It has a maximum speed of 13 knots — or about 15 mph — but it travels 3 knots, or 3.5 mph, when towing its array of monitoring equipment. It carries a crew of 20 mariners, five technicians and as many as 20 Navy personnel.

The Chinese ships involved were a Navy intelligence collection ship, a Bureau of Maritime Fisheries Patrol Vessel, a State Oceanographic Administration patrol vessel and two small Chinese-flagged trawlers, the statement said.
