Final answer:
The U.S. policy of containing China in the 1950s and 60s involved military intervention through strengthening American armed forces and providing military support to countries in the region.
Step-by-step explanation:
In the 1950s and 60s, the U.S. policy of containing China included military intervention. While economic aid and cooperation, diplomatic recognition, and cultural exchange programs were utilized with other countries, the U.S. government took a militaristic approach when it came to China. This involved strengthening American armed forces and providing military support to countries in the region, such as aiding the nationalist forces in Taiwan against the Communist government in China.
