Rio Tinto is currently in negotiations with steel makers Baosteel Group and Shougang Group over a new pricing mechanism for its Australian ore, however the key customers haven't yet agreed to the terms. Rio Tinto's seeking of a new pricing mechanism for its iron ore with Chinese customers is justified given the dramatic lift in coking coal prices, chief executive Jean-Sebastian Jacques believes.
