Typhoon Kajiki has brought strong winds and heavy rain to southern China's Hainan island and parts of Guangdong province.

Typhoon Kajiki has made landfall after Vietnam ordered more than half a million people to evacuate their homes in anticipation of widespread destruction.

Vietnam announced plans to evacuate more than half a million people and ordered boats to stay ashore, while the southern Chinese city of Sanya closed businesses and public transport on Sunday as both braced for an intensifying Typhoon Kajiki.
