The United States is ramping up sanctions against Russia to deprive Moscow's "war machine" of money and components needed to sustain its invasion of Ukraine, but curbing a main source of funding, Russian energy exports, will take time, U.S. Deputy Treasury Secretary Wally Adeyemo told Reuters on Thursday.

The United States and its allies have "a lot more that we can and we will do" to punish Moscow if Russia fails to halt its invasion, Adeyemo told Reuters in an interview.
