China’s global arms push continues. As my colleague Franz-Stefan Gady reported last week, China is showcasing some of its military hardware to potential buyers in the Persian Gulf at the ongoing Dubai Air Show. The jewel in China’s crown at the Air Show is the FC-31 stealth fighter, basically a replica of the F-35 Joint Strike Fighter–supposedly constructed with designs stolen from Lockheed-Martin back in 2009. Another interesting piece of news from Dubai is that China and Pakistanapparently have found an unnamed buyer for their jointly developed JF-17 “Thunder” fighter.

China has several other interesting items on show in Dubai. Shaanxi Aircraft Corporation has been promoting its venerable Y-8C and its modern Y-9 (basically the People’s Liberation Army Air Force’s version of a C-130 Hercules). According to Vasiliy Kachin at the Moscow Center for Analysis of Strategies and Technology, Iran has apparently ordered an undisclosed number of these aircraft. Iran has already airlifted troops to battlefields in Syria and has a requirement for more heavy transport aircraft.

But when it comes to promoting advanced defense products, China faces challenges in trying to sell to this part of the Middle East. In an interview with Defense News, Richard Bitzinger, a military transformation specialist at Singapore’s S. Rajaratnam School of International Studies, says that items like fighter jets and helicopters are just too complicated, and few countries will want to “take a chance on Chinese products, when it comes to performance and quality.”

“Keep in mind, too, that Russia is really coming back as an arms exporter, and it is going to compete head-to-head with China in many of these third-world markets,” Bitzinger said. “In that regard, Russia has a leg up, since it has long-term relationship with many of the countries in places like the Middle East and Central Asia.”
