In talks with President Gotabaya Rajapaksa on Wednesday, Khan highlighted Buddhist heritage sites in Pakistan and stressed the building of cultural ties, the Pakistan Embassy said in a statement.
“Pakistan probably has one of the greatest Buddhist heritages in the world and we invite people from Sri Lanka to visit them,” Khan said a day earlier after meeting with Prime Minister Mahinda Rajapaksa
Khan is making a two-day official visit to Sri Lanka which began Tuesday.
Buddhists account for more than 70% of Sri Lanka's 22 million people. Ethnic minority Tamils, who are mainly Hindu, comprise about 15% and 9% are Muslims.
Khan said northern Pakistan is the center of the ancient Buddhist Gandhara civilization and that a 40-foot (12-meter) sleeping Buddha statue was recently discovered there.
“We are planning a Buddhist trail ... with all the Buddhist great shrines and Buddhist places," he said.
Prime Minister Mahinda Rajapaksa is the older brother of President Gotabaya Rajapaksa.
