Boeing Co and Indonesian's Lion Air signed on Friday an agreement for the Southeast Asian nation's largest domestic carrier to buy $21.7 billion worth of jets from the U.S. aircraft maker. The deal was announced by the White House during a trip by U.S. President Barack Obama to the Asia-Pacific. Executives signed the deal in Bali, Indonesia, where Obama will attend the East Asia summit.

This is an example of how we are going to achieve the long-term goals I set of doubling our exports over the next several years, Obama said after attending the signing ceremony.

He described the deal as a win-win situation for consumers in the region and U.S. workers and said his administration and the Ex-Im bank played a key role in facilitating the deal.

The Democrat is under intense pressure ahead of a re-election battle in 2012 to show progress in boosting the economy and bringing down the 9 percent U.S. unemployment rate.

During his nine-day Asia-Pacific tour that began in Hawaii, Obama has sought to emphasize an agenda of expanding trade ties with Asia, the world's fastest-growing region. (Reporting by Caren Bohan; Editing by Muralikumar Anantharaman)
