In the Mao era, China dealt with Africa as part of a show of solidarity with countries that shared some of China's experience of Western oppression. However, these links were fostered in an ideologically charged time, when China sought to display affinity with other socialist countries and to demonstrate an almost nihilistic aversion to the institutions and norms of international relations. Although it joined the UN in 1971, any real alteration of China's foreign policy did not come until the Deng-initiated reforms post-1979.
