"In March 2017, taking a step forward, Saudi Arabia’s King Abdulaziz City for Science and Technology and China Aerospace Science and Technology Corp. signed a partnership deal to produce China’s CH-4 Unmanned Aerial Vehicle (UAV), which is similar to the U.S.-made MQ-1 Predator drone.. Saudi Arabia has been in possession of such drones since 2014, as has Iraq. This Saudi facility will likely operate as a hub “for manufacturing and servicing for other CH-4 operators in the Middle East, including Egypt, Iraq and Jordan.” Likewise, the UAE, a coalition partner in the Saudi-led air campaign against Houthi rebels in Yemen since 2015, imported Chinese-made Wing Loong I drones in 2011, and became the first customer of the Wing Loong II drone in 2017. This is more evidence of the hassle-free deals that China has struck with its Middle Eastern clients, as the U.S. has become more reluctant to supply its traditional partners with similar systems. Beijing’s further involvement in exporting such weapons, in the long run, could run against the U.S. arms business as well as its strategic interests in the region.
....
The gradually growing arms trade, indeed, is giving further leeway to China to expand its strategic footprint in the region, where its economic investments and technological assistance are massive and welcomed. In the Middle East, China has found a lucrative market for some of its defense products, while the former will continue to rely on Beijing’s economic and technological assistance for economic modernization programs and infrastructure developments. It is this strong convergence of mutual interests that is going to fuel the growth of Chinese arms sales to the region."

America's main problem is that its currency, the dollar is too expensive.
This make American labor cost is to high.
