In 1966 all foreign missionaries were expelled by the Burmese government, but the Burmese Protestant church has become a vibrant missionary-sending movement, despite financial limitations and geographic isolation. The growth in conversions to Christianity can also be attributed to changes in generations of minority groups from animism to Christianity, or as a reaction to Buddhist nationalism, generally associated with the Burmese majority. The percentage of Christians in the Chin minority group grew from 35% in 1966 to 90% in 2010 and in the Kachin minority group, it grew from 40% in 1966 to 90~95% in 2010.
