China's high-speed railway technologies are looking for increased export markets as Chinese companies acquire independent intellectual property.

Earlier last year, California's lower house approved financing for a new railway line that will link the cities of San Francisco and Los Angeles at an estimated cost of $68 billion. China's Ministry of Railways had announced that Chinese companies would form a group to enter the bidding.

"One of the favorite bids for the project has come from a Chinese consortium, and it is China which has built more high-tech, high-speed railway links than anyone else in the last year," BBC News reported in 2011 about China's bids.
