MONROVIA -- A new team of 140 Chinese policemen have arrived in the Liberian capital Monrovia and will carry out UN peacekeeping mission in the country where 85 percent of the population live below the international poverty line.

The riot police squad is tasked with maintaining security and order in Monrovia by patrolling, handling emergencies and guarding important figures.

The team, formed principally of border police from east China's Zhejiang province, have been trained in international law, weaponry application, bodyguarding and English.

Liberia had witnessed political instability since 1980 when a military coup overthrew the True-Whing Party leadership, which led to the deaths of between 250,000 and 520,000 people and devastated the country's economy. A peace agreement in 2003 led to democratic election in 2005.
