Chinese smartphone maker Xiaomi plots global growth

In less than five years, the Beijing-based Xiaomi has gone from start-up to global player in the smartphone market.

It is China's biggest seller of smartphones, and is the third largest in the world, behind Samsung and Apple, according to International Data Corporation (IDC).

Key to its global ambitions is its business outside China.

In April, it launched its Mi 4i phone in India, its top market after mainland China.

On Tuesday, the model was introduced in Hong Kong and Singapore.

Latin America will be next, with phones to be launched in Brazil in the coming weeks.

Hugo Barra, vice president of Xiaomi Global, explained to the BBC's Juliana Liu why the developed markets of UK, US and Europe will have to wait.
