Since the late 1970s, China has experienced an unprecedented economic boom, and is today's fastest growing major economy. Its economic reforms of 1978 allowed large amounts of capital to flow within the country, spurring the economy into a period of breakneck growth. Tens of millions of rural Chinese have been drawn into China's cities looking for work, and countless businesses-foreign and domestic-have sprung up in China, each eager to grab a piece of China's 1.3 billion-strong customer base: the world's largest. It is an exciting time.

Using location photography and beautifully crafted dramatic reconstruction, the two part documentary begins by telling the story of the known voyages of Zheng He. In the second part, the programme examines Menzies's evidence that he claims is proof that the Chinese discovered America long before Columbus.
