Why is it difficult for China people to travel to Sint Maarten?

Hainan is the largest special economic zone and the only tropical island province in China. Since the establishment of provincial special economic zones for more than 20 years, remarkable achievements have been made in economic and social development. However, due to the late start of development and poor foundation, the overall level of economic and social development in Hainan is still low, and the task of protecting the ecological environment, adjusting the economic structure and promoting scientific development is very arduous. Giving full play to Hainan's location and resource advantages, building Hainan into an international tourist island and creating an internationally competitive tourist destination are important measures for Hainan to accelerate the development of modern service industry and achieve sound and rapid economic and social development, and have an important demonstration role in adjusting and optimizing the economic structure and changing the development mode throughout the country.
