China's biggest airline says it's buying 110 jets from Boeing in a deal worth about $10 billion.

China Southern Airlines said Thursday that it's buying 30 Boeing 737 Next Generation jets and 50 737 Max aircraft.

The company also said its Xiamen Airlines unit is buying 30 of Boeing's 737 Max jets.

The Next Generation planes have a list price of $81.2 million while the Max series aircraft sells for $96.1 million.

However, airlines usually negotiate discounts on such deals.

The order comes two months after Boeing signed a deal with a Chinese state-owned company to build its first final assembly plant in China, for 737 aircraft.

State-owned China Southern is the country's biggest airline by passengers and fleet size.
