Defence spokesman Yang Yujun said the PLA would take all steps to protect national security.
However, a US official said on Tuesday that in future it would send more warships to sail close to the artificial islands built by Beijing in the South China Sea,
Here we take a look at the three ships involved in Tuesday’s incident in disputed waters.
USS Lassen (DDG82)
A guided-missile destroyer – a small, fast warship, especially one equipped for a defensive role against submarines and aircraft – which is often used to escort larger vessels in a fleet or battle group.
The USS Lassen is part of the USS Carl Vinson Battle Group. It has been a frequent guest to the South China Sea and is known to be familiar with the operations of People’s Liberation Army’s Navy in the region.
It was built in Pascagoula, Mississippi in the US and launched in 1999. Its original homeport was in San Diego, before it moved its new homeport in Yokosuka, Japan, from where it has been in active service ever since.
In 2009, Lasen collided with a Japanese 14-tonne pleasure boat in Yokosuka.
In July 2009 media reports said Lassen was tracking the North Korean ship Kang Nam 1, which was suspected of carrying contraband.
