Four Chinese companies have revealed plans to float on the Hong Kong exchange to raise a total of $1.7bn (€1.2bn), as domestic firms increasingly look to offer their shares to overseas investors.

Shenzhen Airlines, a domestic passenger carrier, is eyeing a $1bn flotation on Hong Kong according to Chinese daily the South China Morning Post. It plans to launch a pre-flotation share offering of $200m this year. The paper said a fund run by Deutsche Bank is interested in buying into the sale.
