Seven of the world's top 10 most highly valued non-US "unicorns" - private companies valued at more than $1 billion each - began in China, according to a report from US consulting firm CB Insights.

Chinese ride-hailing company Didi Chuxing is the world's second-most highly valued unicorn, just behind the US-based Uber, another car-hailing service provider.

Although more than 50 percent of the world's 214 unicorn companies are located in the United States, an increasing number of unicorns have been popping up in global markets.

China, home to 55 unicorns, has become the world's second-richest country in unicorn companies, followed by India and the UK.

India's largest unicorn Flipkart, an e-commerce platform with Chinese internet giant Tencent as its strategic investor, is the world's fifth most highly valued non-US unicorn.

Let's take a look at the top 10 most highly valued unicorns outside the US.
