By comparing satellite images, Chinese think tank South China Sea Strategic Situation Probing Initiative (SCSPI) stated on Monday that Vietnam is developing military facilities on Pearson Reef (known to the Chinese as Bisheng Jiao and Đảo Phan Vinh to the Vietnamese) in the South Sea, posing a military threat to Fiery Cross Reef (Yongshu Jiao to the Chinese, and Đá Chữ Thập to the Vietnamese). The SCSPI, which has long been tracking the South Sea issues, posted two satellite photos on Twitter on October 25, indicating that Vietnam has built a number of administrative and military facilities, and there are still land under construction.

The Pearson Reef is about 100km away from China-controlled Fiery Cross Reef. Previously, China reclaimed land on the Fiery Cross Reef and expanded it significantly. However, if there is a localized war, the new type of rockets equipped by Vietnam can be launched from Pearson Reef to paralyze Fiery Cross Reef’s airport, port and other facilities, causing the Chinese navy and air force to lose support in the South Sea, and in that case, China can only rely on aircraft carriers or long-range supplies from Hainan Island, which will be very detrimental to the Chinese Navy.

China’s strategy in this has always been facing challenges from Vietnam. Without strategic containment against Vietnam, China is facing uncertainties. If international situation drives Vietnam to confront China, wars will be erupted in the South Sea over the islands and reefs, and there will be chain reactions that lead to unresolvable and complicated situations.
