The Chinese government currently spends more than any other Antarctic state on new infrastructure such as bases, planes, and icebreakers. China has doubled its number of bases in Antarctica and now has four research stations, two field camps, and three air fields there, and it is getting ready to build a fifth base in the Ross Sea region, not far from the USA’s McMurdo Station. China has the second largest number of citizens visiting and working in Antarctica. Chinese polar scientists have made significant geographical discoveries and named hundreds of geographical sites. The Chinese Antarctic science programme has fully self-sufficient air, land, and sea capabilities in Antarctica. It has two ice-strengthened vessels operating in Antarctic waters, with a further vessel under construction. China’s icebreaker has circumnavigated the continent twice, mapping uncharted Antarctic waters.
