WEC has been influential in the movement for countries once known as 'missionary-receiving' lands to become 'missionary-sending' lands. WEC International missionary Leslie Brierley visited Brazil in 1962 to survey that land for its missionary-sending potential. Later, in 1972–73, he and Bob Harvey, also of WEC, began touring Brazil giving seminars promoting the idea. The idea has since matured in Brazil and spread to many other countries. Many indigenous mission agencies were formed as a result, and Brierley formed a "global strategy for launching mission movements in non-Western countries."
