JinkoSolar has formally terminated its 4 GW Hai Ha solar cell project in Vietnam, citing US anti-dumping duties that were undermining the export economy. The company will continue other Vietnamese operations and shift focus to local supply chains and markets in Asia Pacific and the Middle East.
JinkoSolar’s Hai Ha solar cell project in Vietnam was formally terminated on March 11, after the investor requested that development be halted and the Quang Ninh Provincial Economic Zone Management Board approved the request under Vietnam’s Investment Law. The authority also revoked the project’s investment certificate No. 3282186668.
The project would be developed by Jinko Energy (Vietnam) Intelligent Manufacturing Co., Ltd., a vehicle set up by one of JinkoSolar’s subsidiaries in Hong Kong, at the Hai Ha Industrial Park in Quang Ninh Province. The facility was planned to reach a capacity of 4 GW of solar cells and 3 GW of module capacity. The project initially had a total planned investment of $1.5 billion when submitted in October 2023, later revised to approximately $294.2 million in January 2024.
The termination followed a formal notice the company filed with the Quang Ninh Administrative Service Center on February 26, 2026. Vietnamese official reports noted that the closure was the investor’s decision and not a government-imposed closure.
A key factor behind the termination was the deteriorating economic situation in the export of Vietnam-made PV products to the United States. In June 2025, the U.S. Department of Commerce issued anti-dumping duties on crystalline silicon PV cells from Vietnam, following positive final determinations from both Commerce and the U.S. International Trade Commission. Under the amended final determination, Jinko Solar (Vietnam) Industries Co., Ltd. assigned an estimated weighted average dumping margin of 125.91% and an adjusted cash deposit rate of 120.38%.
The US trade measures appear to have undermined the strategic rationale for the Hai Ha project, which was part of JinkoSolar’s Southeast Asian manufacturing footprint partly aimed at the US market. The termination reflects not only a project-level decision, but also a broader reassessment of the economics of Southeast Asian solar energy production amid rising U.S. tariffs.
This step does not mean a complete withdrawal from Vietnam. JinkoSolar continues to operate other manufacturing facilities in the country, including solar cell and wafer fabs, with approximately 10 GW of integrated n-type capacity remaining online. The company will also reportedly pivot its global strategy toward more localized supply chains and a greater focus on markets such as the Middle East and the broader Asia-Pacific region.
JinkoSolar is now expected to complete the project termination process, including handling the ongoing construction works, tax and social insurance obligations and land leasing matters. The case highlights how trade policy is reshaping overseas production for Chinese solar companies, pushing investment decisions toward profitability, market access, and regional diversification rather than simple capacity expansion.
