He announced that the Carribean side will be playing three Twenty20 internationals in the tour.
International Cricket Council (ICC) had decided that a World XI team will visit Pakistan to play three T-20 matches in September this year.
Sri Lanka Cricket (SLC) President Thilanga Sumathipala has stated that Sri Lanka will be ready to tour Pakistan for at least one T20I in Lahore ‘if all logistical and operational plans fall in place’.
In 2015, Zimbabwe became the first international cricket team to visit Pakistan since an attack on the Sri Lankan team in 2009.
The second edition of Pakistan Super League (PSL) was also held at Lahore.
International footballers, wrestlers and bodybuilders have toured Pakistan this year.
Since the attacks Pakistan has only hosted a limited-over series against Zimbabwe in 2015 while Bangladesh, the West Indies, Sri Lanka and Ireland turned down offers over security fears.
But security has dramatically improved across Pakistan in the last two years, signalling hopes for the slow revival of international sport in the country.
In March, Pakistan successfully hosted the PSL final in Lahore with English players Dawid Malan and Chris Jordan, West Indies’ Darren Sammy and Marlon Samuels and South Africa’s Morne van Wyk and Zimbabwe’s Sean Ervine competing.
The match’s success pushed the PCB to expedite efforts to convince more teams to play in Pakistan.
“We will play a full series with Sri Lanka in the UAE after which Sri Lanka will come to Lahore for a Twenty20, so things are shaping up,” said the PCB boss.
Sethi said he will announce the names of World XI players in the coming days.
