China Southern Airlines

American Airlines has agreed to pay $200 million for a stake in China Southern Airlines, the biggest of China's three major state-owned carriers, in a bid for a bigger share of the country's growing travel market.

American and China Southern will expand commercial cooperation, possibly in sales, airport facilities and code-sharing, the Chinese airline said in an announcement Tuesday through the Hong Kong stock exchange. It said the deal represents 2.76 percent of China Southern's shares and requires regulatory approval.
