Vale says not seeking to buy fertilizer assets
Brazilian mining company Vale, the world's top iron ore miner, said on Friday it is not seeking to buy fertilizer assets following rumors it was planning a bid for US-based fertilizer company Mosaic .
China shouldn't bid for Potash Corp. of Saskatchewan Inc. because countering BHP Billiton Ltd.'s $40-billion offer would cost too much and isn't needed to secure fertilizer supply, a state researcher said.
