Chinese Officials Condemned US Ship's Passage.

Chinese officials have condemned a US ship's passage near

disputed islands in the South China Sea as "illegal".
The guided-missile destroyer USS Lassen breached the 12-nautical mile zone China claims around Subi and Mischief reefs in the Spratly archipelago.
The freedom of navigation operation is a serious challenge to China's claims over the artificial islands.
Its foreign ministry said the ship had been warned and characterised the act as a "threat to China's sovereignty".

Lu Kang, the spokesman, added that Beijing would "resolutely respond to any country's deliberately provocative actions" and that the ship had been "tracked and warned" while on the mission to deliberately enter the disputed waters.
Meanwhile, US Defence Department spokesman Cdr Bill Urban said that "the United States is conducting routine operations in the South China Sea in accordance with international law".
The move was welcomed by several countries in the East Asia region, including the Philippines and Japan.

Dredging

China claims most of the South and East China seas. Other countries in South-East Asia have competing claims for the Spratly Islands, Paracel Islands and Scarborough Shoal, which are thought to have resource-rich waters around them.

The reefs, which were submerged, were turned into islands by China by a massive dredging project which began in late 2013.

China says this work is legal and in a meeting with US President Barack Obama last month in Washington, President Xi Jinping said China had "no intention to militarise" the islands.
But Washington believes Beijing is constructing military facilities, designed to reinforce its disputed claim to most of the region - a major shipping zone.
