US Treasury Secretary Yellen: US open to all tools if China invaded Taiwan

The United States is open to all tools if China invades Taiwan, US Treasury Secretary Janet Yellen said on Wednesday, reported Bloomberg. The US is monitoring attempts to use crypto to evade sanctions, she added, referring to sanctions on Russia. 

A senior Biden administration official just announced that the US is "dramatically escalating" the financial shock on Russia by cutting off the country's largest banks. The US is to impose full blocking sanctions on Russia's Sberbank and Alfa Bank, the official added, while US President Joe Biden is also set to sign a new executive order banning all new investment in Russia.
