Chinese technology giant Xiaomi has said it plans to be the world's biggest smartphone maker within three years.

The comments by the Beijing-based firm's boss come after it recently overtook Apple to become the second largest mobile brand.

South Korea's Samsung Electronics currently holds the number one spot, BBC reported.

Xiaomi's founder and chief executive Lei Jun was speaking ahead of the launch of the company's new Mix 4 handset.

He was making his annual speech during an online event as the company celebrated the 10th anniversary of its first smartphone launch.
