Khrushchev's famous shoe-banging outburst at the UN was in response to a delegate from what nation?

Nikita Sergeyevich Khrushchev (15 April 1894 – 11 September 1971) was a Soviet statesman who led the Soviet Union during part of the Cold War as the First Secretary of the Communist Party of the Soviet Union from 1953 to 1964, and as Chairman of the Council of Ministers, or Premier, from 1958 to 1964. Khrushchev was responsible for the de-Stalinization of the Soviet Union, for backing the progress of the early Soviet space program, and for several relatively liberal reforms in areas of domestic policy. Khrushchev's party colleagues removed him from power in 1964, replacing him with Leonid Brezhnev as First Secretary and Alexei Kosygin as Premier.

The notorious shoe-banging incident occurred during a debate on 12 October over a Soviet resolution decrying colonialism. Khrushchev was infuriated by a statement of the Filipino delegate Lorenzo Sumulong charging the Soviets with employing a double standard by decrying colonialism while dominating Eastern Europe. Khrushchev demanded the right to reply immediately and accused Sumulong of being "a fawning lackey of the American imperialists". Sumulong resumed his speech and accused the Soviets of hypocrisy. Khrushchev yanked off his shoe and began banging it on his desk. This behavior by Khrushchev scandalized his delegation.
