Former World Bank boss: 'The world could look like it did in 1900'

Countries are pulling back from free trade and that could be a danger to world peace, according to former World Bank president Robert Zoellick.

He says the US, China and Europe are all "taking care of the people at home" and putting up barriers to international trade.

Speaking to Asia Business Report's Sharanjit Leyl, he said this could take the world back to the year 1900 when "great powers were in competition".
