just do it

China's two largest railway construction companies plan to sell shares in Shanghai and Hong Kong before the end of the year to capitalise on soaring valuations and make up for a shortfall in government funding for the state-owned sector.

China Railway Group, the third-largest construction contractor in the world and the largest in Asia by revenue last year, is set to raise at least $3.8bn in an initial public offering in Shanghai and a secondary offering in Hong Kong that will help pay for rapid expansion.
