China plans to sign a deal next month confirming five airlines’ orders for 50 Boeing 787 Dreamliners, a Chinese news agency said Friday. The Boeing Co. said it was still negotiating with those carriers and a sixth airline to seal commitments for a total of 60 orders placed in January.

Airlines involved in the $6 billion deal, reported by the official Xinhua News Agency, were the national flag carrier Air China, Shanghai-based China Eastern Airlines, Hainan Airlines, Xiamen Airlines and Shanghai Airlines.

In January, those airlines and a sixth, China Southern, announced a deal for 60 787s worth $7.2 billion.
