In power, Castro sided with the Soviet Union in the 1961 Sino-Soviet split while Guevara sympathized with China. Perhaps accelerated by this divide, the latter man shifted his energies away from Cuba to adventurism, promoting guerrilla foco theory overseas.

Guevara's attempt to forge an insurgency in Bolivia led to his capture and subsequent execution in 1967.
