Billionaire Pony Ma Huateng has called for the Greater Bay Area of Guangdong, Hong Kong and Macao to be turned into China's Silicon Valley and a "mecca for talent".

The chief executive officer and co-founder of online giant Tencent Holdings Ltd made it clear he would like to see more policy support for the plan at the Guangdong-Hong Kong-Macao Greater Bay Area Forum in Hong Kong on Tuesday.

Ma felt governments in the area should switch from being competitive to collaborative and join forces to attract the best global talent in high-tech businesses.
