CGTN's special programming, Tides of Change, which tracks China's blue economy, has kicked off. CGTN reporters explore the country's coast, looking at life, beautiful scenery, and of course, policies to boost sustainable economic development. The first stop is Hainan's Yangpu Port — the model port for free trade on the island province. Our reporter Xu Xinchen reports from there with a guest Ye Yang, the Deputy Director of Office of the Free Trade Port Working Committee of Yangpu Economic Development Zone in Hainan Province.
