An area of particular concern to potential sales of the JF-17 is China's weakness in purchase and resale of aircraft engines. This could complicate a purchase decision for potential customers. The K-8, for example, is powered by the Ivchenko AI-25 turbofan or the Honeywell TFE731, a powerplant originally developed by Garrett for business jets, while the JF-17 is powered by Russia's Klimov RD-93. Historically, a major criticism of Russian aviation equipment is the lack of spares and delays in conducting major repairs. The Royal Malaysian Air Force logistics officer told Flightglobal in an interview at the at 2011's LIMA air show in Langkawi that “….it could take one year for a MiG-29 engine to be repaired if were sent back to Russia”, adding: "The MiG-29 are a maintenance nightmare." That alone should be enough to make potential JF-17 customers have second thoughts.
"In a worst-case scenario, customers must worry not only about maintaining good relations with China, but also with Russia. This substantially reduces China's independent leverage in the lucrative and strategically potent area of military aircraft sales, which Russians, Europeans and Americans are loath to cede to China. China will find it particularly challenging to make headway in Russia's former Soviet republics, with Moscow using its political clout in the region to ensure sales for Russian airframes.
However the one bright point in all of this is that the cost of effective combat aircraft has gotten prohibitively expensive. Many 3rd world or developing nation Air Forces are faced with a choice between fewer or no military aircraft second hand aircraft and/or Chinese versions, growing numbers of countries in Africa, the Middle East and Latin America are likely to consider the China option
Maybe Beijing willing offer creative financing and other support packages that other established aircraft producers may not offer.
