China has announced another rise in public disturbances in 2005, as rapid economic growth continued to spark social unrest.
China has cracked down hard on some of the protests
The Public Security Ministry said it handled 87,000 public disturbances last year, a rise of more than 6% on 2004.
The figures come amid growing anger at official corruption and several high-profile land disputes between authorities and villagers.
China's leaders see social unrest as the biggest threat to their rule.

A ministry spokesman said the figure did not refer just to mass protests, but to all criminal cases linked to public disorder, including mob gatherings, obstruction of justice, fighting and trouble-making.
China's official statistics are unreliable.
But a BBC correspondent in Beijing, Louisa Lim, says the trend suggests growing social instability in China, as an ever-widening wealth gap leaves many excluded from the country's economic boom.
A key cause of some of the most high-profile unrest has been land seizures by corrupt local officials, who have sometimes failed to give adequate compensation to villagers.
In the most recent incident, villagers said police in the southern province of Guangdong beat locals protesting over a land grab.
Villagers said a teenage girl died in the protest, though officials denied this.
Guangdong also saw a violent protest over land requisitions in December, in Dongzhou village.
Paramilitary forces opened fire on demonstrators, killing three people according to official accounts, and as many as 30, according to villagers.
