It is hard to miss the self-congratulatory mood in Beijing’s corridors of power these days. The Chinese Communist party was practically written off after its army crushed the pro-democracy movement in Tiananmen Square on June 4 1989. At home, it faced a shocked and resentful population. Internationally, it was isolated. The fall of communism in the former Soviet bloc further demoralised its members. A sense of impending doom permeated Beijing.

Twenty years later, things could hardly be more different. China is riding high as a new economic and geopolitical giant. The party’s rule has never felt more secure.
