If true, this is a huge intelligence coup for China. Our stealth technology is far ahead of other nations - especially China - and for Pakistan to allow a potential enemy to study an advanced technological innovation is a monstrous betrayal.

Washington Post:

Pakistan gave China access to the previously unknown U.S. "stealth" helicopter that crashed during the commando raid that killed Osama bin Laden in May despite explicit requests from the CIA not to, the Financial Times reported Sunday.

The disclosure, if confirmed, is likely to further shake the U.S.-Pakistan relationship, which has been improving slightly of late after hitting its lowest point in decades following the bin Laden killing in a Pakistani garrison city.

"The U.S. now has information that Pakistan, particularly the ISI, gave access to the Chinese military to the downed helicopter in Abbottabad," the paper quoted a person "in intelligence circles" as saying on its Web site.

The ISI, the Inter-Services Intelligence Directorate, is Pakistan's top spy agency.

The report said Pakistan, which enjoys a close relationship with China, allowed Chinese intelligence officials to take pictures of the crashed aircraft as well as samples of its special "skin," which allowed the helicopter to evade Pakistani radar.

The ISI denies the charge, but it very well might have given the Chinese military a glimpse of the copter due to their anger over the bin Laden raid.

We won't be sure until we determine whether China has developed countermeasures that could shoot down the stealth copter. No doubt such a system would be a hot item on the international arms market.
