U.S. President Joe Biden is getting ready to deliver on a key campaign promise by convening a Summit for Democracy: a first-of-its kind gathering of more than 100 countries to help stop democratic backsliding and erosion of rights and freedoms worldwide.

But rights advocates are questioning whether the virtual event can push those world leaders who are invited, some accused of harboring authoritarian tendencies, to take meaningful action.

"If the summit is to be anything more than just another meeting, each attendee, including the United States, will need to follow through on meaningful commitments on democracy and rights issues in the year ahead," said Annie Boyajian, vice president for policy and advocacy at Freedom House, a nonprofit group specializing in human rights and democracy.
