PARIS, Nov 20: The Boeing aircraft company, locked in a bitter struggle with European rival Airbus, scored major sales victories in China and Dubai on Sunday by winning orders worth 13.7 billion dollars.

The United Arab Emirates flagship carrier Emirates announced at the Dubai air show an order for 42 long-haul, twin-engined Boeing 777 aircraft valued at 9.7 billion dollars.

At the same time, coinciding with a visit to Beijing by US President George W. Bush, Boeing announced an order for 70 737 single-aisle jets to China valued at four billion dollars.

A Boeing spokesman said the sale was part of a broader deal to deliver to China up to 150 of the 737s, which are used for short- and medium-haul routes.—AFP
