TOKYO (Reuters) - Canada's Alimentation Couche-Tard ( ANCTF ) said on Tuesday it is confident in attaining the U.S. regulatory approvals required to buy out Japan's Seven & i Holdings ( SVNDF ) after the latter said antitrust law would be a barrier to any deal.

In a statement Couche-Tard said it had submitted a revised non binding proposal in January as per Seven & i's ( SVNDF ) request and continues to be disappointed with the limited engagement thus far.

"Our proposal presents shareholders with a clear economic value, unlike 7&i's repeatedly revised plan as announced last week," the statement said.
