Following
World War II, the
Korean Peninsula was divided into
South Korea, supported by the
United States, and
North Korea, supported by the
Soviet Union and
China. Neither side recognized the legitimacy of the other's regime. After the 1961
May 16 coup, the new South Korean leader
Park Chung Hee urged for an increase in military spending and for action to be taken against North Korea. The North Korean leadership feared a South Korean invasion and turned to the Soviet Union and China for support. Kim Il Sung arrived in Beijing in 1961 to sign the treaty just a few days after signing the North Korean-Soviet Mutual Aid and Cooperation Friendship Treaty (). The treaty was signed by North Korean Premier
Kim Il Sung and Chinese Premier
Zhou Enlai on 11 July 1961 in Beijing, It was approved by
Liu Shaoqi, then Chairman of China, on 30 August. The
Standing Committee of the Supreme People's Assembly of North Korea approved it on 23 August. On 10 September, Zhou Enlai and Kim Il-sung, as representatives of both sides, exchanged instruments of ratification in Pyongyang, the capital of North Korea, after which the treaty came into effect. == Provisions of the treaty ==
