China plans to buy 200 Boeing aircraft worth an estimated $19 billion, the White House said Wednesday during a state visit by President Hu Jintao to the United States.

The order includes 737 medium-range and 777 long-range jets, Boeing said in a statement confirming the deal.

The aircraft will be delivered over the three-year period 2011-2013, Boeing said.

"Boeing is pleased to have received final approval today from the Chinese Government confirming a $19 billion aircraft agreement," it said.

Boeing jets comprise more than half of all commercial jetliners operating in China, the company said.

If forecast that China's air travel and cargo system will need 4,330 new aircraft over the next 20 years, worth more than $480 billion.

"We value China's support for our products and its confidence in Boeing," said Boeing Commercial Airplanes CEO Jim Albaugh.
