Answer: China
Notes: China separated Hainan Island from mainland customs to support entry into a trans-Pacific trade deal and develop a Hong Kong-style commercial hub. Hainan is China’s southernmost tropical island, located in the northeastern Beibu Gulf, across the Qiongzhou Strait. It is known as the “Hawaii of China”. It covers 35,400 sq. km, the largest island administered by China. The island has a population of about 10 million; its capital Haikou is called the “Coconut City.”
