well hope you know that the pakistani gave an F16 china to evaluate so that the tech can be used in J 10 and there are also rumours that pakistan got M11 missile in exchange of their F16 so, we never know what the real things is but ya an F16 some how ended up in china through pakistan i guess
here is an example of Chinese developed their new helicopter

China illegally uses Canadian engine for attack helicopter
Analysis: China illegally uses Canadian engine for combat helicopter
HONG KONG, Oct. 5
ANDREI CHANG
Column: Military Might
China has officially released the photo of a mysterious Z-10 combat helicopter that was indigenously developed over a 15-year period. An official brochure on the helicopter shows that the Z-10 uses a PT6C-67C engine imported from Pratt &Whitney Canada.
Although some Western military observers had suspected that China might be attempting to use the PT6C-67C for its Z-10, this official announcement still comes as a surprise. As a military embargo against Beijing has been in place since the 1989 Tiananmen incident, this Canadian engine case may make Washington call for a tighter policy, especially regarding NATO countries.
A source from the P&W said the company did not know anything about the Z-10, claiming that the Chinese purchased its products only for use in civilian helicopters, according to the contract. Those engines were supposed to be used for the development of new 6-ton civilian helicopters and the assembly of AB-139 civilian helicopters. This indicates that China has illegally changed the purpose of the engines from a civilian to a military use.
Western military observers say that China could have manufactured more than eight Z-10s so far. The third one has just completed test flights. China has a plan to purchase more engines, allegedly for the development of new civilian 6-ton helicopters, which will allow them to build at least another seven Z-10s from now.
It is not known yet whether future Z-10s will be manufactured in large batches or will continue to use this imported engine. China may switch to an indigenously developed new engine or an upgraded version of the WZ-9 engine for mass production.
Who else has helped China to develop its Z-10 combat helicopter? An authoritative source from the South African Denel Company said that before 2001, Chinese representatives paid frequent visits to the company. They also invited company staff to visit the Chinese cities of Changhe and Harbin. The Chinese visitors were from the army, the air force and various military industrial enterprises.
"Every time, they requested to look at our Rooivalk combat helicopter. They took away all possible technical materials and took a large number of photos as well as videotapes," the source said. "They also asked so many questions. Their exchanges with us focused on the flight stability and performance features of airborne cannons. We learned from this that the Chinese were experiencing technical difficulties in the design of the Z-10, especially its maneuverability."
In 2001, the Chinese abruptly proposed to purchase one Rooivalk, but the company refused to sell it. "If they needed, they could have paid for formal technical consultation fees," the source said. "Why did they propose to buy only one helicopter? Wasn't it obvious that they intended to thoroughly study the structure of the Rooivalk? We rejected the proposal. After 2001, they never come back to us again."
Where did the Chinese go after 2001? With this question, the author visited Eurocopter Company, where a senior company official claimed, "We can say in a responsible manner that we did not have any contact with the Chinese on the design of the Z-10. The Chinese did not ask us to get involved in the project, and it would have been impossible for us to do so."
The author also visited AgustaWestland Italy. After persistent questioning, a company source acknowledged that they were involved in part of the Z-10 project, but did not reveal any details. In recent years, AgustaWestland has been considered China's closest partner among Western helicopter production enterprises. The two sides have even established a joint venture.
Under cover of jointly producing civilian helicopters, AgustaWestland has very likely given China technical information on the basic redesign of the Z-10. Accordingly, some of the configuration of the Z-10 is very close to AgustaWestland's A-129 combat helicopter. As for the weapon systems on the Z-10, most of them were manufactured in China, including the new HJ-10 anti tank missile and TY-90 air-to-air missile.

KABUL, Afghanistan — Four U.S. military helicopter engines worth a combined $13.2 million are missing in the Afghanistan-Pakistan region, the American military said Wednesday.
The engines were being shipped over land from the main U.S. base at Bagram and were destined for Fort Bragg, N.C., where the 82nd Airborne is based, said U.S. spokeswoman Lt. Col. Rumi Nielson-Green.
"The components went missing en route to port — the exact location is undetermined," Nielson-Green said.
The parts went missing sometime before the 101st Airborne arrived to replace the 82nd in early April, she said. They were being shipped by a Pakistani trucking company.
Militants in both countries frequently target convoys of goods destined for NATO bases.
In March, nearly 40 trucks carrying fuel to U.S.-led forces in Afghanistan were destroyed in two bomb attacks on the Pakistani border. The bombings wounded about 100 people.
Pakistan's top military spokesman, Maj. Gen. Athar Abbas, said the reports of the missing helicopter parts were under investigation, but he said that U.S. forces had not contacted Pakistan officials about the matter.
The U.S. is not disclosing what kind of engines they were to prevent any criminals or insurgents from getting additional information.

Z-9WE Light Attack Helicopter
China Aviation Industry Corporation-owned Harbin Aircraft Industry Group Co. Ltd. has revealed that the Z-9WE light attack helicopter is available for export. (here)
The Z-9WE is a militarized variant of the H425 civilian helicopter platform. The H425 was, in turn, developed as a civilian variant of the Z-9 military utility helicopter. The H425 is powered by a pair of Arriel-II turboshaft engines whereas the Z-9 is powered by domestic WZ8C engines.
The two Z-9 attack helicopters recently exported to Kenya are likely the new Z-9WE variant instead of the domestic Z-9WA. (here)
