Chinese drones "have bigger payloads, which means they can carry more weapons" than their competitors, Shi Wen, chief drone designer at the China Academy of Aerospace Aerodynamics, told the China Daily newspaper.
Chinese companies dominate the global market for commercial drones, but the rare interview is a sign Beijing is seeking to promote itself as a manufacturer of unmanned military surveillance and killing machines.
Shi did not specify the countries involved, the numbers sold or the total value of the deals, but said the academy's most valuable sale was worth "hundreds of millions of US dollars".
"One of our clients in Africa uses each of its CH-3s about 100 hours on average each month," Shi told the newspaper, which is published by the government.
The academy is seeking an export licence for a new CH-5 model capable of launching air-to-surface missiles and laser-guided bombs, Shi added.
The drone made its first test flight in August, the newspaper said.
China has also exported smaller unarmed search aircraft, it said, citing a report last year that the academy would export about 200 drones.
SIPRI's February report added that Chinese weapons chiefly went to other Asian countries, with Pakistan the main recipient.
