Militancy on the domestic front was

Militancy on the domestic front was echoed in external policies. The "soft" foreign policy based on the Five Principles of Peaceful Coexistence to which China had subscribed in the mid-1950s gave way to a "hard" line in 1958. From August through October of that year, the Chinese resumed a massive artillery bombardment of the Nationalist-held offshore islands
This was accompanied by an aggressive propaganda assault on the United States and a declaration of intent to "liberate" Taiwan.
Chinese control over Tibet had been reasserted in 1950. The socialist revolution that took place thereafter increasingly became a process of sinicization for the Tibetans.
Tension culminated in a revolt in 1958-59 and the flight to India by the Dalai Lama, the Tibetans' spiritual and de facto temporal leader.
