It has been 50 years for the United Nations General Assembly Resolution 2758 to recognize the People's Republic of China as the only legitimate representative of China to the United Nations and remove the Republic of China, or Taiwan, from the United Nations. China's President Xi Jinping said the resolution still rings true. However, some US officials discussed Taiwan's participation at the UN as an observer.
Oct. 25, 2021, marks the 50th anniversary of the United Nations General Assembly resolution 2758. China's President Xi Jinping gave an address in Beijing. According to Chinese media, Xi said the UN Resolution 2758, which stated that the People's Republic of China is the only legitimate government representing China in the United Nations was passed with an overwhelming majority back in 1971. Xi stressed that the international rules can only be determined by the 193 member states of the UN in whole and not by any individual member states. Xi hit back at the remarks made by US Deputy Assistant Secretary of State Rick Waters earlier saying that China has been misusing UN Resolution 2758 to stop Taiwan from playing a big role in the organization.
Chen I-hsin, Legislator (KMT)："Chapter 5 within the UN Charter still retains the Republic of China as one of the permanent members of the Security Council, so in the future, if we could return to the UN, we would have to return under the name of the Republic of China."
Wang Ting-yu, Legislator (DPP)："It is best to maintain a political gray zone. There is a "red line" on war and regional safety. Invading Taiwan will cross the red line. This seems to be a clear diplomatic trend that is agreed and followed by countries across the globe, which helps greatly in keeping Taiwan safe and stable."
The UN General Assembly Resolution 2758 was proposed by 23 member states led by Albania during the 26th general assembly meeting in 1971 and was passed the same year. It recognized the People's Republic of China as the only legitimate representative of China to the United Nations and removed the Republic of China from the United Nations. However, the US has been actively voicing support for Taiwan lately and high-level US diplomats have recently met with the Taiwanese Ministry of Foreign Affairs via videocall to discuss Taiwan's participation at the UN and other international forums.
Weng Ming-hsien, Dean of School of Strategic Studies, Tamkang University："Joining the UN means that the UN, as well as the rest of the world, recognize Taiwan as a sovereign state. China has always tried to block Taiwan from participating in the UN. US' support and assistance are very helpful to Taiwan's presence in the international community."
One scholar says that political reasons rise above all else in the decision of Taiwan's participation in the UN. It is currently very difficult for Taiwan to participate in the UN since China is a permanent member of the UN Security Council and has the right to veto. Tensions between China and the US have lingered since the trade war erupted during the Trump administration and whether tensions would escalate needs to be observed.
聯合國大會第2758號決議滿50年，中國國家主席習近平在北京發表談話，根據中國官媒指出，習近平指出，50年的今天，聯合國大會以壓倒性多數通過第2758號決議，承認中華人民共和國政府代表是中國在聯合國的唯一合法代表，還強調，國際規則只能由聯合國193個會員國共同制定，不能由個別國家和國家集團來決定，直接回應美國國務院亞太副助卿華自強，先前曾指中國誤用2758號決議。
國民黨立委 陳以信表示：「在聯合國憲章當中第五條，仍然存在中華民國，所以未來如果要重返聯合國，我們仍然應該以中華民國的名義，來重返聯合國。」
民進黨立委 王定宇表示：「政治上，維持模糊的彈性，在軍事跟區域安全上，那條紅線，不容侵犯台灣的紅線，走向戰略清晰，這是這一個階段，國際外交發展的趨勢。這樣的發展對台灣和平、穩定，有莫大幫助。」
聯合國大會第2758號決議文，是1971年第26屆聯合國大會會議，阿爾巴尼亞等23國提案表決通過「恢復中華人民共和國在聯合國組織中的合法權利問題」，承認中華人民共和國政府是中國在聯合國組織的唯一合法代表，也是「中華民國退出聯合國」的日子。不過，美國近來頻頻展現挺台立場，不只公布台美討論擴大國際參與的會議內容，不少官員也表態，希望台灣以觀察員身分參與聯合國。
淡江大學國際事務與戰略研究所所長 翁明賢表示：「加入聯合國，就等於對全球國家承認，是一個主權獨立的一個國家。中國對台灣參與聯合國，會有很多的杯葛。美國出面來讓台灣能夠，不管用什麼名義來參與的話，將對台灣有助益。」
學者認為若台灣成功加入聯合國，等同主權被國際認可，但台灣議題在聯合國是政治層面高於專業層面，而且中國在聯合國安理會具有否決權，台灣要加入的困難度很高，美國是否會拉高美中對峙緊張態勢，還有待觀察。
