The chairman of China National Chemical Corp (ChemChina) said on Sunday he hopes to re-list Italy’s Pirelli (PECI.MI) on the Italian stock exchange after his firm agreed earlier this month to acquire the world’s fifth-largest tire maker. Ren Jianxin also warned that a counterbid for Pirelli would hurt the Italian firm’s investors and long-term strategy. ChemChina has agreed to become majority owner of Pirelli as part of a multi-layered 7.3 billion euro ($8 billion) deal, putting one of Italy’s storied manufacturing names in Chinese hands.
