UN Peacekeeping, as an instrument developed for peace, has made a significant contribution to world peace. In 1971, China recovered its legitimate seat in the UN and began to play a more active role in international affairs. After reform and opening up began in 1978, China gradually increased its involvement in UN peacekeeping affairs. In April 1990, China's armed forces dispatched five military observers to the United Nations Truce Supervision Organization (UNTSO) and embarked on a new voyage as a participant in the UNPKOs. In the past three decades, China's armed forces have engaged in the UNPKOs with courage and determination, always aspiring to fulfill their missions of meeting the responsibilities of a major country, safeguarding world peace, and contributing to the building of a community with a shared future for mankind. China's Blue Helmets have become a key force in UN peacekeeping.
