"We are all delighted to see the resumption of global cricket in Pakistan and we look forward to the success of this series to further build on its success by motivating the other teams to visit Pakistan", said Pakistan captain.
Ongoing security issues have made it hard for Pakistan to host worldwide games, with "home" matches instead taking place in the United Arab Emirates.
"But I am confident that through this tour, more cricket will come our way, and we will do our best to win for home fans".
The series, which has been renamed as the Independence Cup, is the first time since 2009 that an worldwide match will take place in Pakistan under the supervision of ICC officials.
In an interview to BBC Urdu, Afridi said he was happy that global cricketers were going to play on Pakistani soil, adding that it would have been even better if Indian players were also included in the World XI team.
New series marks return of foreign sportsmen after matches in Pakistan stopped after 2009 deadly attack in Lahore.
Shops and restaurants around the venue will be shut while spectators will have to pass through multiple security checkpoints.
To a query regarding any security issue the visitors have faced, Imran said: "There is absolutely no problem here. Thank you very much".More news: Xiaomi's Mi Notebook Pro takes on Apple's Macbook

"Sport can create hope where once there was only despair", said one of the world's greatest leaders, Nelson Mandela.
Sarfraz said that if Indian players had also toured Pakistan he would have been happier.
Security has dramatically improved in Pakistan in recent years, but militant groups retain the ability to carry out spectacular attacks and officials are taking no chances.
The team of World XI arrived at the Lahore airport today and were given a warm welcome by PCB Chairman, Najam Sethi. "I am very excited to have cricket back home after a long time and it is a moment of joy", Sarfraz said.
Addressing the media following the arrival of World XI side in Lahore, du Plessis insisted that he wants to be a part of the history by contributing in the revival of worldwide cricket in Pakistan. "Everybody had the courage and the confidence to play here and that was an absolutely essential (factor) for this series".
Amir debuted in 2009 but has never played at home while Babar Azam, Ahmed Shehzad, and Imad Wasim played their first worldwide in 2015 against Zimbabwe.
Du Plessis repeatedly alluded to the end of his playing days - he even said he was unlikely to be on a tour to Pakistan with South Africa because he would have retired by then - and spoke of the importance of this tour for the legacy he'd like to leave behind.
To a question he expressed the optimism that World XI will rise to the occasion and display quality cricket to put Pakistan which is a talented tam under pressure. Samuel Badree will join the squad on Monday as he was part of the Caribbean Premier League final on Sunday.
