Which dispute was resolved between Pakistan and China in 1963?

The question focuses on a significant diplomatic achievement between Pakistan and China. In 1963, Pakistan and China successfully resolved their Boundary issue through the Sino-Pakistan Frontier Agreement. This agreement demarcated the border between the two countries, primarily in the Karakoram mountain range, and was a cornerstone in establishing strong bilateral relations.

• The Water issue, particularly concerning the Indus Waters Treaty, was primarily a dispute between Pakistan and India, resolved in 1960.
• The Kashmir issue remains a long-standing territorial dispute between Pakistan and India, not directly resolved with China in 1963.
• Therefore, 'None of these' is incorrect as a specific and crucial dispute was indeed resolved.
