The International Cricket Council says it wants to keep a check on the number of international Twenty20 ties despite the game's increasing appeal.
ICC chief executive Haroon Lorgat says his personal view is that it should be a domestic event rather than an international event.
Some experts feel that too many Twenty20 internationals, perfect for new fans thanks to its three-hour duration, could hurt the following for the longer versions of the game.
Lorgat was reacting to comments by Australian coach Tim Nielsen, who has urged the ICC to permit regular bilateral series for Twenty20 games if teams are to take the format seriously.
Australia, champions in the last three World Cups and the number one test team, lost early in the inaugural World Twenty20 in 2007 against surprise champions India.
Currently, teams are allowed one Twenty20 international on a bilateral tour. However, the lucrative Indian Premier League involving players from major cricketing nations has proved a hit.
