that China's July 2012 actions to unilaterally assert control of disputed territories in the South China Sea "are contrary to agreed upon principles with regard to resolving disputes and impede a peaceful resolution." Chinese dredging activities In 2014 Janes reported that during 2013–2014 China had begun a substantial program of dredging and land reclamation at three sites in the Spratlys. Janes concluded that 'The strategic effect of China's dredging and land reclamation makes it the most significant change to the South China Sea dispute since the 1988 Johnson South Reef Skirmish. If completed as envisioned in the CGI designs, China will have its first airstrip in the Spratly islands – and a base from which to impose its interpretation of the surrounding features' sovereignty'. Janes also noted that in contrast to the previous construction projections of other countries in the Spratlys, 'The main difference between these activities and China's is that they modified existing land masses, while Beijing is constructing islands out of reefs that for the most part were under water at high tide'. There is no known official term for the projects; the phrase "Great Wall of Sand" was first used by Harry Harris, commander of the US Pacific Fleet, in March 2015. 2015 construction of an airfield at Fiery Cross Reef In April 2015 new satellite imagery revealed that China was rapidly constructing an airfield at Fiery Cross Reef, in addition to its ongoing dredging activities in the Spratlys. In September, China had completed a 3125-metre runway. Claims and their basis Brunei Brunei claims the part of the South China Sea nearest to it as part of its continental shelf and exclusive economic zone (EEZ). In 1984, Brunei declared an EEZ encompassing the above-water islets it claims in Louisa Reef. Brunei does not practice military control in the area. Basis of Brunei's claim Brunei's claims to the reef are based on the United Nations Convention on the Law of the Sea (UNCLOS). Brunei states that the southern part of the Spratly Islands chain is actually a part of its continental shelf, and therefore a part of its territory and resources. Malaysia Malaysia claims a small number of islands in the Spratly Islands and its claims cover only the islands included in its exclusive economic zone of 200 miles as defined by the United Nations Convention on the Law of the Sea. Malaysia has militarily occupied five islands
