Wall street has suffered its worst trading day of the year with the Dow Jones index plunging 768 points. 

This has occurred under the backdrop of the continuing trade wars between the US and China, with the Dow Jones suffering after China devalued the yuan to its lowest level in more than a decade. 

Market analysts said Beijing’s latest move comes after the US president Donald Trump vowed last week to impose ten percent tarrifs on the remaining $300 billion dollars of Chinese imports.
