In March 2010, Cambodia is to host a three-week-long multinational peacekeeping exercise as part of the Global Peace Operations Initiative (GPOI), said Prak Sokhon, a secretary of state at the Council of Ministers. He said the US- and UN-sponsored exercise will involve a total of 2,000 military and civil participants from at least 20 different countries. The operation will involve both field training and an exercise for military command.
