Fifty years ago, on October 25, the lawful seat of the People's Republic of China (PRC) was restored in the United Nations (UN), marking a milestone event in the history of the international organization.

Starting a new course of China's UN story this year, the country has vowed that it will stay true to its original aspiration after the vicissitudes of the past half-century, calling for joint efforts to build a community with a shared future for mankind.

China has always been a builder of world peace, contributor to global development and defender of the international order, said President Xi Jinping in his speech at a commemorative meeting marking the historical event on Monday.
