Joe Biden marked his 100th day in office this week. The 46th U.S. president has wasted little time signing orders on diplomacy, racial equity and civil rights. Although largely welcomed by activists, others warn much more needs to be done and fast. For more comments on Joe Biden's approaches in the last 100 days, Global Watch talked with Josef Gregory Mahoney, a professor of Politics at East China Normal University. He assessed Biden's handling of domestic and international issues and said Joe Biden was seeking new opportunities for diplomacy to resolve issues with China step by step.
