57 Boeing 737s for Xiamen Airlines

The domestic transportation market of China is amazingly huge. For example, more tracks are needed for China's bullet train.
As for the civil aviation, more planes are needed.
Xiamen Airlines of China is negotiating with Boeing to buy 25 additional 737-800 single-aisle jets, according to China’s Xinhua news agency. The order would be worth $1.8 billion at list prices.
Boeing already has delivered five new 737-800s to Xiamen , and the airline has 27 more on order. With the addition of a few leased jets, Xiamen plans to have 60 new 737-800s by 2013, Xinhua said.
Its growth is fueled by regional economic development and increasing business ties between Xiamen and Taiwan.
