Three decades after the Chinese Communist Party's bloody crackdown on pro-democracy student protests in Tiananmen Square, the memory survives — despite the country's attempts to stamp it out.

The June 4, 1989, crackdown in Beijing was a stark reminder of the political realities of China's one-party system, even as the world's most populous country embarked on reforms and opening up under then-paramount leader Deng Xiaoping.

Since then, the West and Japan have sought to balance human rights concerns with reaping the rewards of economic relations with China.
