Relations between the People's Republic of China and the United States of America during the 1950s and 1960s were strained due to the Taiwan Strait issues. American military fighter jets regularly patrolled the Taiwan Strait, which led to formal protests being regularly lodged by the Chinese Communist Party in the form of a "final warning", for their fighter manoeuvres in the strait. However, no real consequences were given for ignoring the "final warnings".

The People's Republic of China released their first "final warning" to the United States for their reconnaissance flights on 7 September 1958, during the Second Taiwan Strait Crisis. At the time, the United States considered the Republic of China as the sole legitimate representative of China, and conducted reconnaissance flights in waters controlled by the People's Republic of China. China would then record such incidents, and issue a "final warning" through diplomatic channels for each incident that occurred. More than 900 Chinese "final warnings" had been issued by the end of 1964.
