Trouble appears to be brewing amongst the Asian nations, including India, with China building a massive strategic underground submarine naval base that could house N-submarines and a host of aircraft carriers on Hainan Island. in South China Sea, south of Hong Kong. The base, being built near the holiday resort of Sanya on Hainan Island's southern tip, was revealed by commercial satellite images on May 3, 2008. According to satellite imagery reported by the Federation of American Scientists and Britain's Daily Telegraph, the base has a sea entrance wide enough to allow submarines to enter the underground facilities with as many as 11 tunnel openings. Beijing seems to have circumspectly designed this new base since it stands at close proximity to vital sea-lanes in the South China Sea and Straits of Malacca. The Chinese are resolute to protect this since 80 per cent of its oil supplies presently move through the channel before traversing the South China Sea to mainland ports. In addition, the location could give China better access to disputed territories, such as the Parcel Islands and Spratly Islands in the South China Sea. Furthermore, the Hainan Island underground base, incidentally, will house the new Shang-class Type 093 nuclear ballistic missile submarines (SSBNs) and the in-class Type-094 SSBNs. Moreover, the new Type 094 Jin-class submarines were captured in the images.
