A sharp sell off in US stocks has spilled over into Asian markets, with technology stocks from the US to China falling the hardest, as investors refocused on slowing global growth, rising bond yields and increasing trade tensions.

Stock indexes in mainland China, South Korea and Japan fell more than 4% apiece on Thursday, with declines accelerating throughout the day. Taiwan’s Taiex index, dominated by semiconductor companies and Apple suppliers, fell the most, dropping 6.3%, its worst slide since January 2008.
