The PCB had been trying to convince foreign teams to restart worldwide cricket back in Pakistan.
Since then, Pakistan hosted two Twenty20 and three one-day internationals against Zimbabwe in 2015 but last year's final of the Pakistan Super League (PSL), three T20 internationals against a World XI and a T20 global match against Sri Lanka helped convince the West Indies.
The south Asian country has remained largely starved of global cricket since the 2009 attacks on a bus carrying Sri Lankan cricketers in Lahore, wounding six players and a British coach and killing eight Pakistanis.
Najam Sethi announced on Sunday that West Indies cricket board has been agreed to play T20 series in Pakistan.
Sethi also had a message for those doubting that the Pakistan Super League 2018 final will be held in Karachi. "Now it is Karachi's turn to rise and shine with PSL3 Final and WI", Sethi wrote in a separate tweet.
Multan skipper Shoaib Malik chose to field first after winning the toss at Dubai International Stadium and his decision quickly backfired as Karachi piled on their highest score in this year's competition - 188 for 3. PSL final and now three more games for Karachi as per routine.
"This will be a one-off series.it will be a loss-making enterprise".
