Past presidents have tried to use "soft power" strategies to bolster the United States' cultural appeal abroad and lend moral weight to the country's standing as the free world's leading alternative to communist or authoritarian systems. Such tactics are not a substitute for military and economic "hard power," foreign affairs analysts said, but can help shape global perceptions of the United States and its motives.

China, which regards itself as one of the world’s oldest civilizations, but one that has been repressed by outsiders, has often made culture a battlefield. It has tussled with its neighbors and rewritten history textbooks. In other instances, soft power skirmishes may be seen as substitutes for hot war. So China’s recent embrace of Japanese movies may be more complicated than audiences falling for the cuteness purveyed by Japan’s cartoon factories.

Connecting China and Western Europe, Poland has been tapped as a key link in the Chinese government's "Belt and Road" initiative. Chinese President Xi Jinping made a stop in Poland back in June, overseeing the signing of around 40 different trade and partnership agreements.

Pyongyang began exporting statues to Africa in the late 1960s, when a wave of independence movements created a new market of ideologically friendly leaders in search of grand symbols to bolster national identity and claims of political legitimacy. North Korea, looking to expand its diplomatic ties vis a vis rival Seoul, initially provided the works for free. It only started selling them from about 2000.
