International migration effectively entered the G20 agenda only in 2015 when the final leader 's declaration of the Antalya Summit described the " ongoing refugee crisis " as a global concern . Nearly one year later at the Hangzhou Summit in September 2016 , G20 leaders reiterated their call for more burden sharing , humanitarian assistance and development funding . They also agreed to " address forced displacement in 2017 with a view to developing concrete actions " and to examine migration issues . However , although the Hamburg Declaration in July 2017 mentions both migration and forced displacement in general terms , it does not propose any " concrete actions " in either area
