Sources said Biden's schedule for Asia is not official until it has been announced and could change. One senior diplomat referred to Indonesia having scheduled the ASEAN summits, which are normally held in November, for September, specifically to make is possible for Biden to attend and then go on to the G20. Sources said Biden was expected to send Vice President Kamala Harris in his place. Policy analysts said another no-show by Biden, who attended ASEAN meetings in Cambodia in November, would call that characterization into question. "Southeast Asia has been impressed that Washington under Biden has stepped up engagement with the region," Hiebert said.
