Lately the tension concerning the South China Sea is rising higher. Given China's land reclamation, there is increasing suspicion about China's strategic intention in this region. As China has conducted massive land reclamation in the South China Sea in a short period of time, China could theoretically build a defense installation there, making its access to the entire area much easier.

Subsequently, the US has indicated its concern that China's move that might possibly hamper the international norm of freedom of navigation. The US is both upset by China's fast and massive land reclamation there, and more concerned about the likelihood that China would consequently perceive its possession of new territory to associated and valuable territorial water and space.

America wants to make sure that artificial islands, based on previous status as low-tide elevation, shall not be entitled to sovereign water and associated space. This may be applicable to Subi Reef, Mischief Reef and Cuarteron Reef etc. Therefore, the Pentagon has dispatched the USS Lassen to within 12 nautical miles of Subi Reef, as a part of its exercise of "Freedom of Navigation". If the US truly doesn't accord recognition of territorial water of these reefs, its ship may enter such close water without citing a right of "innocent passage". According to American press reports, a US strategic bomber B52 has even reached as close as 2nm of the Cuarteron Reef, claiming afterward to have been "drifting off course" due to bad weather, possibly to test China's response.

While the US may have its reason for suspicion and testing Chinese response, China has its own logic of distrusting America. China's arguments could be summarized as the following. First, China has claimed all rock features within U-shaped lines since 1947 and has for decades met no opposition from either those South China Sea-ringing states or other major powers including the US. Second, dozens of these islands and islets of the Spratly have later been occupied by some ASEAN members but China is still willing to "shelve difference and co-develop (the region)". Third, though those other claimants have already reclaimed a number of the islands and islets under their occupation and militarized them, they have not been blamed at all. Therefore, China feels puzzled about why it is singled out for reclaiming some of its own rock features?
