Not only is China seeking foreign joint venture partners to manufacture wind turbines, it will give domestically made turbines preferential treatment over imported turbines in competitive bidding. The State Planning Commission of China is formally seeking partners in the United States to manufacture wind turbines, according to the US Department of Commerce. Wind and other renewables were last year designated a priority for development in China and the seeking of foreign joint venture partners was expected (Windpower Monthly, January 1997). The potential partners are being asked to help with the manufacture of 300 kW and 600 kW wind turbines with two large Chinese firms, China National Aeroengine Corp and China First Tractor and Construction Machinery Bloc. First Tractor has already built wind turbines together with Germany's Husumer Schiffswerft, which received German government backing for the project (Windpower Monthly, January 1996). First Tractor is aiming to build 200, HSW 250 kW machines, eventually with 80% Chinese content. The blades for the machines are being made by Aeropropellor Factory of China. Wind companies sought by China as partners must be sound financially, have a good record of operation and a high reputation for production quality. The company must be experienced in manufacturing large scale turbines, which must also have international certification.
