“China's testing of a newly-built airfield is nothing more than an effort by the country to better serve the needs of the great many vessels and seafarers using one of the world's busiest shipping lanes,” Wang Haiqing wrote for an article in Xinhua.
The Chinese government has stated that the runway would conform to civil aviation standards and other improved facilities intended at facilitating search and rescue, disaster prevention and reduction and navigation safety.
It will by no means undermine the peace and stability of the region. Instead, it will greatly enhance the safety of the vessels on the vast South China Sea by “facilitating search and rescue, disaster prevention and reduction, and research and conservation from a Chinese land base.”
As noted by the Chinese media the airfield shouldn't be a cause for concern for anybody especially as there has never been any problem regarding freedom of navigation and over-flight in the South China Sea and all countries are authorized to do so under international law.
