The decision by one of the nation’s largest banks to admit to $3 billion in potential losses on foreign loans could mean less lending by commercial banks to developing countries and increasing the pressure on multigovernment lenders to supply the funds.

看到og里有几个地方都说要用admit to sth 但是admit本身好像可以直接加宾语，请问admit sth 和admit to sth 有何不同？ 多谢！
