China's president has been discussing trade at the World Economic Forum in Davos. Daisy Guo is a Chinese entrepreneur who tells us she welcomes Mr Xi's stance. Meanwhile, Anthony Scaramucci, a senior adviser to Donald Trump, explains the president-elect's approach to trade. Also in the programme, businesses in the UK have been responding to prime minister Theresa May's vision for a "clean" Brexit, confirming that Britain will leave the European single market. We get the perspective of Christopher Nieper from clothing manufacturers David Nieper, who voted to leave the EU, and Hayden Wood, co-founder of the energy sector start-up Bulb, who voted to remain. Plus the BBC's Joe Miller meets a group of arctic and antarctic scientists hoping to raise the profile of climate change at the World Economic Forum.
