The launch of the Hainan special customs zone in December 2025 is believed to mark a milestone development with the ambition to position Hainan not just as a regional duty-free zone, but more importantly, as a testing ground for further opening up at the institutional level.
Companies in Hainan now have free flow of capital with their overseas business partners by establishing an Electronic Fence Account (EF Account), officially known as a multi-functional free trade account, at Hainan branches of major Chinese banks. The transactions can be done online.
According to the People’s Bank of China, the country’s central bank, since the launch of this operation in May 2024 to the end of November 2025, 729 EF accounts had been established with 11 banks, with a combined transaction settlement of 295 billion yuan (US$42b) with 80 countries and regions, covering transactions such as foreign exchange trading of banks, cross-border trade payment, loans and external debts. According to Zheng Yuhua, general manager of Hainan Special Economic Zone East-Lake Hi-Tech Investment, an investment and development vehicle company focusing on fostering high-tech and industrial clusters, the new policies are particularly appealing to two types of firms: processing enterprises that source raw materials overseas while selling into the Chinese mainland, and export-oriented companies seeking to use Hainan as a gateway to global markets.
“Industries characterized by high tariffs, high value added and relatively low logistics costs, such as bio-pharmaceutical companies that rely on imported inputs and equipment, as well as high-end manufacturers dependent on imported core components, stand to benefit most from the policies,” Zheng told NewsChina.
Zheng’s company operates Donghu Hi-Tech Haikou Bio-City, which has attracted more than 170 companies across sectors such as bio-pharmaceuticals and medical devices, including multinational corporations listed on the Fortune Global 500.
Mingyang Smart Energy, a leading player in offshore wind power, was among the early corporate entrants to Hainan. In December 2021, the company began construction of a high-end offshore wind equipment manufacturing base in the province, which has since entered production.
A Mingyang executive told NewsChina that compared with coastal bases on the mainland, Hainan offers irreplaceable advantages for serving international markets, particularly in Southeast Asia and Oceania, thanks to its geographical location, policy openness and institutional innovation.
Following the full launch of Hainan customs zone, the executive said that import costs for specialized steel, composite materials, core components and intelligent manufacturing and maintenance equipment required for large offshore turbines are expected to fall significantly. Combined with the 15 percent corporate income tax incentive, these advantages are especially compelling for the capital-intensive wind power sector, where investment horizons are long and returns take time to materialize.
