China country profile
China is the world's most populous country. It has a continuous culture stretching back nearly 4,000 years and originated many of the foundations of the modern world.
The People's Republic of China (PRC) was founded in 1949 after the Communist Party defeated the nationalist Kuomintang, who retreated to Taiwan, creating two rival Chinese states - the PRC on the mainland and the Republic of China based on Taiwan.
After stagnating for decades under the rigid authoritarian socialism of founder Mao Zedong, China reformed its economy along partly capitalist lines to make it one of the world's fastest-growing, as well its leading exporter. China is now a major overseas investor, and is pursuing an increasingly assertive foreign and defence policy.
But economic change has not been matched by political reform, and the Communist Party retains a tight grip on political life and much of wider society.

President: Xi Jinping
Xi Jinping came to power in 2012-3 as the hand-picked heir of predecessor Hu Jintao, and is expected to lead China for the next decade.
Since taking over, he has concentrated power in his hands, in a move seen as a turning away from the people's republic's traditional system of collective leadership, and has sought to present a modern face to China and the world.
The main themes of his leadership have been economic reform to boost market forces, as well as an anti-corruption campaign that, apart from boosting his popularity, has claimed several potential heavyweight party rivals.
Mr Xi rejects Western ideas of constitutional democracy and human rights as models for China, and his government moved to silence voices critical of one-party rule, especially on social media.

China is the largest media market in the world.
Outlets operate under tight Communist Party control. The opening-up of the industry has extended to distribution and advertising, but not necessarily to editorial content.
Beijing tries to limit access to foreign news by restricting rebroadcasting and the reach of satellite TV, and by blocking websites using an extensive filtering system known as the "Great Firewall".
With 731 million users, China has the world's largest online population. Three powerful companies - Baidu, Alibaba and Tencent - dominate the market.
