Activists protesting corporate profits, environmental abuses, poor working conditions and the Israel-Hamas war are among those planning to march in downtown San Francisco on Sunday, united in their opposition to a global trade summit that will bring leaders from nearly two dozen countries, including U.S. President Joe Biden.

Protests are expected throughout this week’s Asia-Pacific Economic Cooperation leaders’ conference, which could draw more than 20,000 attendees, including hundreds of international journalists. The No to APEC coalition, made up of more than 100 grassroots groups, says trade deals struck at summits such as APEC exploit workers and their families.
