Washington: China has developed an active cyber espionage programme and is targeting US computer networks to obtain sensitive data, a Congressional panel has warned.
"China has an active cyber espionage programme through which it is targeting US government and commercial computers," the US-China Economic and Security Review Commission said in its annual report to the US Congress.
The report claims that Chinese hackers are spying on the US government, defence contractors and businesses and cautions that Washington must upgrade its intelligence and homeland security system to thwart such attempts.

"China is stealing vast amounts of sensitive information from US computer networks," said Larry Wortzel, chairman of the Commission.
There are 250 hacker groups in China, with some of those hackers trained by Chinese military academies. If nothing is done to stem these hacking groups' threat, the current US conventional military dominance over China could disappear, the report warns.
