Internet giant Google Inc on Tuesday made a shock threat to quit China, the world’s biggest Internet market by number of users, after hackers accessed human rights activists’ e-mail accounts.

“These attacks and the surveillance they have uncovered — combined with attempts over the past year to further limit free speech on the Web — have led us to conclude that we should review the feasibility of our business operations in China,” Google chief legal officer David Drummond said in a statement.
