Loss-making shipping company Nanjing Tanker Corp will be delisted from the Shanghai Stock Exchange after a five-day grace period, marking the first time for a company backed by the central government to be dropped from a domestic exchange. The delisting comes after the government allowed China's first-ever public bond default in March and underscores the difficulties facing domestic companies saddled with record debt in a slowing economy. The delisting had been widely anticipated after the company said in January it was poised to post its fourth straight year of loss, breaching exchange rules. A statement carried on the Shanghai exchange's official microblog on Friday said Nanjing Tanker will be delisted after booking losses from 2010 to 2013.
