Asian stocks have fallen as worries about the coronavirus pandemic eclipsed hopes that major stimulus plans would ease the impact of the outbreak.

It came after Wall Street's main indexes rebounded by more than 5% on Tuesday following Monday's steep falls.

In the US, the Trump administration outlined a $1 trillion (£830bn) package to support the world's biggest economy.

At the same time the UK has revealed details of its own stimulus measures, including £330bn of business loans, reports BBC.

Japan's benchmark Nikkei 225 lost 1.7%, the Hang Seng in Hong was down by 1.9%, and China's Shanghai Composite fell by 0.5%. US stock market futures were also indicating a weaker open for Wall Street.
