According to Sethi, the PCB has reached an agreement with the cricket boards of other countries at this week's executive board meeting of the ICC in Dubai.
Sethi also announced that Pakistan would be hosting the next meeting of the Asian Cricket Council next year in Pakistan and he would chair that meeting.
"One of the decisions reached at the ICC meeting is that Pakistan will nominate the next chairman of the ICC after the BCCI takes its turn this year," Sethi said.
He estimated that these series would earn Pakistan approximately 3000 million rupees over the eight years.
"This also allows us to now sell the broadcasting and other rights for our home series for the coming years on long-term basis," he added.
Sethi said that all the boards including the BCCI had agreed to sign the agreements with Pakistan for next eight years.
Asked by a reporter what guarantee was there that India would adhere to these agreements, Sethi said that if the agreements were not signed and made legally binding than the PCB would withdraw its conditional support for 'the Big Three'.
