Which top-level Indian leader visited China in 1979 after which diplomatic relations were restored between the two countries?

Atal Behari Vajpayee

The process of normalizing relations between India and China spanned over a decade. The year 1976 marked the restoration of full diplomatic ties between these two nations. Notably, Atal Behari Vajpayee, who held the position of External Affairs Minister at that time, undertook a significant visit to China in 1979. Subsequently, Rajiv Gandhi became the first Prime Minister after Nehru to visit China. From that point onward, the focus has predominantly shifted towards fostering trade relations between India and China.
