U.S. President Joe Biden is getting down to business. He has launched his coronavirus plan and signed 10 executive orders on his second day in office, including new rules on masks and quarantine for international travel. CGTN spoke to Einar Tangen, an independent current affairs commentator, who said that domestic issues will dominate Biden's first 100 days in office. Tangen also talked about Sino-U.S. relations, noting that it is going to take some time for trust-building, as China looks to reset ties.
