China US Sub Accident

China on Tuesday accused the U.S. of a “lack of transparency and responsibility” regarding an accident in the South China Sea involving a Navy submarine last month.

At a daily briefing, Foreign Ministry spokesman Wang Wenbin said the U.S. should provide full details of the incident that has revived the dispute between the two countries over the strategic waterway.

“We once again urge the U.S. to give a detailed account of the accident,” he said.

Wang described what he called a “lack of transparency and responsibility” by the U.S. in following up with the incident.

He said the U.S. has so far failed to offer “a clear explanation" of what the Navy nuclear submarine was doing in the area, as well as “the specific location of the accident, whether it was in another country’s exclusive economic zone or even territorial waters, whether it caused a nuclear leak or damaged marine environment.”

China claims sovereignty over virtually the entire marine area, through which trillions of dollars of international trade pass each year. Six governments in all claim islands, atolls and exclusive economic zones in the sea, while the U.S. insists that freedom of navigation be maintained, reinforcing that with regular military flights and Naval patrols and training missions around the region.

Two Navy officials speaking on condition of anonymity on Monday said the service had determined the nuclear powered USS Connecticut struck a seamount, or underwater mountain.

The Navy has yet to fully explain how or why the sub struck the seamount or to reveal the extent of damage to the Seawolf-class submarine.

The Navy has said the submarine’s nuclear reactor and propulsion system were not damaged. The collision caused a small number of moderate and minor injuries to the crew. USNI News, which was first to report that the sub had struck a seamount, said damage to the forward section of the submarine damaged its ballast tanks.

The incident happened on Oct. 2 but was not reported by the Navy until five days later. The vessel sailed to Guam for a damage assessment, where it remains.
