When China closed its doors to foreign missionaries in 1948, FEBC moved its Asian base of operations to the Philippines. FEBC’s first broadcasts over local station KZAS went on the air on June 4, 1948 in Manila.  International broadcasts to China started on July 27, 1949 with the help of Chinese Filipino Christians and soon expanded to most of Southeast Asia. By the end of 1949, FEBC had 27 languages on the air.
