Ninety-five riot police from China have arrived in Haiti to help restore order in the Caribbean nation plagued with gang and political violence.
The police joined a small advance team of Chinese who arrived last month and will become part of a Brazilian-led UN peacekeeping mission to stabilise the country. More than 50 people have died in violence over the past two weeks.
Former president Jean-Bertrand Aristide fled Haiti in February, forced out by a month-long armed rebellion and US and French pressure to quit.
UN officials have been urging contributing countries to step up efforts to send in troops to join the peacekeepers and help the interim government that took over from Mr Aristide cope with worsening unrest in the poorest country in the Americas.
The UN force so far has just 2,600 soldiers, a fraction of the 6,700 troops and 1,600 police authorised for Haiti. The UN mission took over peacekeeping in Haiti in June from a UN-sanctioned multinational force led by US Marines.
Violence has hit the capital since September and interim Prime Minister Gerard Latortue has accused Mr Aristide's Lavalas Family party of masterminding the unrest in order to undermine the government - charges Lavalas has rejected.
