In 2006, PZL-Świdnik entered into an agreement with China's Jiujiang Hongying Technology Development Ltd. which aimed for the establishment of an SW4 assembly line in Jiujiang, China. In December 2008, a type certification for the SW-4 was issued by the Civil Aviation Administration of China. In late February 2010, the maiden flight of the first SW-4 to be co-produced in China took place; in the same month, PZL Swidnik announced an agreement to produce 150 helicopters, an unspecified number of which being the SW-4, were to be produced for the Chinese market at Jiujiang. By March 2015, a total of five co-produced SW-4s had been delivered to Chinese customers.
