Great Wall Of Sand being constructed in the contested waters of the South China Sea is feared to raise military confrontations among nations claiming jurisdiction of the area.

 A top U.S. official reported that China has built more than 4 square kilometers (1.5 square miles) of artificial landmass of the Great Wall Of Sand.

US Pacific Fleet Commander Admiral Harry Harris reported China's land reclamation on Tuesday night in a speech in Australia. Harris stated that China has built huge landmass by covering the waters and corals with sands tagging it as the Great Wall Of Sand.

"When one looks at China's pattern of provocative actions towards smaller claimant states - the lack of clarity on its sweeping nine-dash line claim that is inconsistent with international law and the deep asymmetry between China's capabilities and those of its smaller neighbors," Harris said.

"Well it's no surprise that the scope and pace of building man-made islands raise serious questions about Chinese intentions."

The Great Wall Of Sand is built over on a reclaimed land on the contested waters being fought over by nations close to China including Philippines, Taiwan and Vietnam.

This is not the first time that China construction is being done in the contested waters. In the recent months before Great Wall Of Sand was reported, Chinese construction in the Spratly Islands were seen when photos of the artificial lands with facilities were seen.

 It seemed that the facilities were built for military purposes, BBC reported.

Harries added that continues claim of several nations in the South China Sea may fuel further tensions. While assuring that U.S. will be in the middle of the negotiations, he reminded that they urge the nations involve of the 2002 China-ASEAN Declaration of Conduct, according to Fox News

With the construction of the Great Wall Of Sand, their intention remains in question as they agreed the 2002 China-ASEAN Declaration of Conduct not to do any activity that may escalate or provoke peace and stability.

Harris assured that U.S. position will remain tight in guarding the stability of the nations that were fighting over the South China Sea. He stated that 60 percent of the U.S. Navy Force will be present in the area by 2020.

Although the U.S. remains in the middle of all nations, the construction of the Great Wall Of Sand was feared by some analysts to be a key indicator of Xi Jinping, the Chinese president's assertive policy.  Xi Jinping has also collided with Japan over disputed islands in the East China Sea, The Telegraph reported.
