China is gaining a bigger share in the international military drone market, with at least one new buyer for its homegrown Wing Loong unmanned aerial vehicle reported this week, according to a senior executive in a State-owned aviation company.

"More than two clients are using Wing Loong, and they have told us that they are very satisfied with the drone's capability and performance," said Ma Zhiping, general manager of China National Aero-Technology Import and Export Corp.

He made the comments at the 15th Aviation Expo/China, which opened in Beijing on Wednesday and lasts four days.
