Sri Lanka are to tour Pakistan for a five-match series of one-day internationals in April and May.
"Sri Lanka has accepted our invitation to play a one-day series,"
Pakistan Cricket Board chairman Dr Nasim Ashraf said on Thursday.
Earlier this week, Bangladesh also agreed to play five one-dayers and a Twenty20 match in Pakistan between April 6th to 22nd.
The two tours have been announced after Australia postponed their trip to Pakistan last week because of security fears.
The series is likely to take place after Mahela Jayawardene's Sri Lankan team finish their tour of the West Indies on April 15th.
The only hitch could be the Indian Premier League (IPL), for which top Sri Lankan players have signed up.
The inaugural IPL is due to be held between April 18th until June 1st.
Cricket Sri Lanka chairman Arjuna Ranatunga added:
"India and Pakistan have always supported us in our needs like big brothers so I am ready to send my team whenever Pakistan want."
The PCB said series dates will be announced shortly.
