On this day, 26 years ago, September 20, 1999 (August 11, 1999 in the lunar calendar), the first batch of peacekeeping troops entered East Timor. On September 20, 1999, the first batch of multinational peacekeeping forces authorized by the United Nations entered East Timor one after another and began to fulfill their mission of restoring peace and security. The first group of 75 Australia officers and soldiers arrived in Dili on the Hercules transport aircraft at 6:45 local time and took control of the airport. Under the escort of helicopter gunships, a total of 2500 soldiers flew to Dili and the eastern city of Baucau one after another, and successfully entered their designated positions as planned without incident. Several Australia warships carrying armored personnel carriers and logistics equipment also arrived in Dili at noon on the 20th. After Major General Cosgrove, commander of the multinational peacekeeping force and an Australia, arrived in Dili at noon on the 20th, he immediately discussed cooperation between the two sides and other related matters with Major General Kiki, the Indonesian military representative in East Timor. An Indonesian military spokesman said in Jakarta on the 20th that after the Indonesian military and the multinational peacekeeping force complete the handover of security work in East Timor, Indonesia will lift the state of emergency imposed in East Timor and gradually withdraw most of its troops, leaving only a small number of troops to help the multinational force carry out peacekeeping operations.
