RIO DE JANEIRO - Brazilian mining company Vale SA said on Thursday the start up of Cia Siderurgica do Pecem (CSP), a Brazilian steel mill being built with Korea’s Posco and Dongkuk Steel Mill Co , will be delayed until the first half of 2016 from the second half of 2015 because of a strike. Vale also said its planned share of capital spending on the 1.5-million-tonne-a-year project fell by more than half to $1.224 billion in the second quarter because CSP will finance $1.49 billion of expenses on its own account.
