US ships must pass through the 12-nautical mile limit around the artificial islands that China illegally built in Truong Sa.- that is the statement of Mr. John McCain, Chairman of the US Senate Armed Services Committee.

“The clearest sign of respect for freedom of navigation is not recognizing the 12-nautical mile limit that is illegally established; the clearest way to demonstrate that it is not recognized is to sail into these international waters…”, Senator McCain said on September 17, just before the visit of Chinese President Xi Jinping to the US.

Up to now, the US has always strongly criticized the illegal reclamation, construction and militarization activities that China has carried out in the East Sea, most recently the construction of a third airstrip on Vanh Khanh Reef. However, according to AP, since 2012, the US Navy has avoided entering the 12-nautical mile area around the illegally built artificial islands in Truong Sa to avoid direct confrontation with China.

“This is a dangerous mistake because it recognizes China's illegal sovereignty claims over the artificial islands,” McCain said during a hearing by US Assistant Secretary of Defense David Shear, then he said forcefully: “We have to go in there.”

The issue of passing through the 12-nautical mile zone to approach the artificial islands that China illegally built has been a hot topic among US defense officials for a long time. US Defense Secretary Ashton Carter has “moved closer to these islands” with the statement that the US will “fly, sail and operate anywhere international law allows.” Mr. McCain quoted that statement in the hearing on September 17.

The 12-nautical mile issue has become even more heated with China building its second and third runways in Truong Sa, despite its previous commitment to stop construction and reclamation in the area.

The Washington Post analyzed that the US will have to consider many different interests when deciding whether to directly confront China or not, because of the extensive economic cooperation between the two sides. In addition, the US still needs China in many political and security issues, such as chemical weapons disarmament in Syria, anti-piracy in the Horn of Africa, control of the nuclear program in North Korea, etc.
