China Communications Construction Co Ltd, the state-controlled builder, has delayed a plan to raise up to 20 billion yuan ($3 billion) via a Shanghai listing, Bloomberg reported on Friday.

China Communications Construction originally aimed to launch the IPO in July or August, Chairman Zhou Jichang was quoted by the news agency as saying.

The Chinese company, already listed in Hong Kong, still hopes to complete the Shanghai listing this year, Zhou was quoted as saying.

A company spokeswoman confirmed Zhou's remarks when contacted by Reuters.

China Communications Construction aimed to issue up to 3.5 billion A-shares in Shanghai, with part of the proceeds used to fund a 1.94 billion yuan takeover of an infrastructure firm, the company said in December.

It already holds a 61.4 percent stake in CRBC International, a builder of roads and bridges.
