Hainan Special: Ecology key to island's success

South China's island province Hainan has become an ideal place for health-conscious tourists, according to a senior official.

Luo Baoming, secretary of the Communist Party of China Hainan provincial committee, invited people around the world to travel to the island, which boasts cleaner air than most of China.

"Please come to Hainan to take a deep breath and swim in the sea during the winter," he told reporters.
