One possible solution would be a “hybrid” staging of the tournament, with India playing its matches outside Pakistan, possibly in the United Arab Emirates. A similar model was used when Pakistan hosted the Asia Cup last year.
However, this raises the possibility of uncertainty over where the knockout matches will be played if India reaches the semi-finals.
And on Friday, Chairman Mohsin Naqvi said the PCB was not ready to accept a hybrid solution.
Pakistan traveled to India to take part in the 2016 T20 World Cup and the 2023 50-over World Cup.
Last month, any suggestion that the tournament could go ahead without India was dismissed by England and Wales cricket Board chief executive Richard Gould.
“If you play the Champions Trophy without India or Pakistan, the broadcasting rights are missing and we have to protect them,” he said.
“If these circumstances arise, we have a number of options available to us. This is a big moment for Pakistan and we hope we can have the greatest possible competition in Pakistan. If that’s not possible, we know there are options.”
There was no international cricket in Pakistan between 2009 and 2015 after gunmen attacked the Sri Lanka team 15 years ago.
Former England assistant coach Paul Farbrace was part of the Sri Lanka team and told BBC Sport that Pakistan “deserves to host international cricket”.
“I fully understand that historical events have marred the situation between the two countries, but the BCCI must realize that this is a bigger issue than whether they want to go to Pakistan or not,” he added .
“From a sporting perspective, this is a fantastic opportunity for India to show that they want to see cricket flourish, rather than saying, 'No, we don't feel like going to Pakistan'. Each of the major countries has to travel to all other countries to grow the game and in this regard India has too much influence.”
