Exclusion of anyone harms efforts to achieve global development goals, UN Deputy Secretary-General Amina Mohammed said on Friday when asked about Taiwan’s bid for UN participation.

World leaders are to meet next week at the annual high-level UN General Assembly, but Taiwan is excluded under a 1971 UN resolution that recognizes the People’s Republic of China (PRC) as the legitimate representative of China to the UN.

Leaders are also to attend a summit on the UN’s Sustainable Development Goals — a global “to-do” list created in 2015 that includes issues such as tackling the climate crisis, achieving gender equality and ending hunger and poverty.
