Which country opposed Pakistan’s membership in the UN?

The question pertains to the historical context of Pakistan's entry into the United Nations. Afghanistan was the sole country to oppose Pakistan's membership in the UN in 1947. This opposition stemmed from Afghanistan's irredentist claims over Pashtun-majority areas along the Durand Line, which it referred to as 'Pashtunistan'.

• Egypt did not oppose Pakistan's UN membership; it maintained cordial relations.
• China, specifically the People's Republic of China, was not established until 1949, and the Republic of China (Taiwan) did not oppose.
• Malaysia was not an independent nation in 1947 and therefore had no role in the UN membership process.

Thus, Afghanistan's historical territorial claims were the direct reason for its opposition.
