A 15-member World XI squad will take part in a 7-day long camp in Dubai before heading to Lahore for the series. At the end of this month, ICC's security team is also arriving.
"Once the World eleven comes to Lahore the Sri Lankan team will also come and it will open the doors for more teams to come to Pakistan", Sethi said.
A World XI tour kicks off in September followed by a short visit by Sri Lanka for a Twenty20 match in October, then a Twenty20 series against the West Indies a month later.
Holding a press conference at the Gaddafi Stadium here, Sethi said that the West Indies Cricket Board (WICB) has accepted the invitation proposal to play three Twenty20 global matches (T20Is) in Pakistan this November.More news: Predicted XI v Everton in the Premier League

Sethi said he will announce the names of World XI players in the coming days, with the team being managed by former England coach Andy Flower. It's a big agenda, we need your prayers and we will open the doors and global teams will come.
Worldwide cricket has not had its presence felt in the country since the attack on the Sri Lankan team bus in Lahore in 2009, which then isolated the insurgency-hit nation in the cricketing sphere. "I wish we could shift it to Karachi, but so far it's only in Lahore", Sethi said.
He said the government security officials had assured them that the recommendations of the security experts who came to Lahore in March had been implemented in the new SOPs. "I am planning to go to Karachi and will meet with security personnel".
Pakistan, who haven't hosted any high-profile worldwide cricket ever since the terror attack on the Sri Lankan team bus in March 2009, lost their share of cricket matches during the 2011 World Cup which was co-hosted by India, Bangladesh and Sri Lanka. That dealt a severe blow to Pakistan's status as a host nation, with the country losing their share of games in the 2011 World Cup, which was scheduled to be jointly hosted by India, Pakistan, Sri Lanka and Bangladesh. The final was held in Lahore and saw couple of global players, including West Indies' Darren Sammy, participate.
