Pakistan and India are both likely to vote against a proposed Twenty20 World Cup at a key meeting next month.
Pakistan and India officials are united in opposition to Twenty20
Pakistan Cricket Board chairman Shaharyar Khan met Indian counterpart Sharad Pawar in Karachi on Sunday.
"Pakistan's view is clear - we don't support this tournament. We will be conveying our views clearly at the ICC executive board meeting," he said.
Pawar said: "We share Pakistan's stance on this. India also does not support a Twenty20 world tournament."
The BCCI boss added: "We feel it dilutes the importance of international cricket."
A meeting of 10 cricket board chief executives proposed the tournament last week, but it needs approval by the ICC Board, which is made up of national board chairmen and presidents.
England are among six or seven countries keen to host the inaugural tournament in 2007.
India are the only Test-playing nation which does not have a domestic Twenty20 competition, showing the success of the format since its launch in England in 2003.
Meanwhile, Shaharyar said the Pakistan and India boards would be finalising their joint 2011 World Cup bid in Delhi on 24 February.
The presidents of the Sri Lankan and Bangladesh boards had also been invited as the plan is to spread the tournament across all four countries.
The two neighbours have also agreed that their domestic national champions will play annually for the Mohammad Nissar Cup, with the first game beginning in Dharamsala on 4 May.
