HONG KONG — China, which has been obsessed with political stability ever since it called out its army to crush a massive albeit peaceful protest in Beijing 22 years ago, is likely to step up repressive tactics against its population in the wake of the toppling of Egypt's President Hosni Mubarak after 18 days of demonstrations.

In 1989, the uprising in Tiananmen Square and around the country went on for seven weeks while the Chinese government refused to accept petitions from the student leaders and ended with a military crackdown that saw hundreds if not thousands of deaths and a manhunt that went on for years for those who had taken part in the protests.

Even today, those who managed to escape the country are not allowed to return on pain of imprisonment.
