Pakistan is one of the first groups of countries that have recognised China. On May 21, 1951, the two countries officially established their diplomatic relations. Since then, China and Pakistan have witnessed smooth development of friendly and neighbourly relations as well as mutually beneficial co-operation. This year both countries are celebrating as a year of friendship to mark 60 years of diplomatic relations. The Pakistan-China friendship is unique in many ways in the recent history of state-to-state relations.
