China tells US to end border reconnaissance

China said that the US should not engage in reconnaissance along China's borders. China's statement came on April 1, the third anniversary of a mid-air collision between a Chinese fighter jet and a US reconnaissance aircraft. The incident resulted in the death of the Chinese fighter pilot and the forced landing of the US plane at a Hainan Province military airport. Chinese officials reiterated that the incident brought serious damage to Sino-US relations.
