（>>793にて引用から抜粋） State-owned Chinese equipment manufacturers initially licensed many of their designs over the last decade from Japan, Germany and France. While Chinese companies have gone on to make many changes and innovations, Japanese executives in particular have grumbled that Chinese technology resembles theirs, raising the possibility of legal challenges if any patents have been violated.
All of the technology would be Chinese, Mr. Zheng said.
But while the ministry has brought costs down through enormous economies of scale, “buy American” pressures could make it hard for China to export the necessary equipment to the United States.
The railways ministry has concluded a framework agreement to license its technology to G.E., which is a world leader in diesel locomotives but has little experience with the electric locomotives needed for high speeds.
According to G.E., the agreement calls for at least 80 percent of the components of any locomotives and system control gear to come from American suppliers, and labor-intensive final assembly would be done in the United States for the American market. China would license its technology and supply engineers as well as up to 20 percent of the components.
