A dump truck takes waste material from Rio Tinto Ltd.'s Paraburdoo mine in Pilbara region, Australia, Dec. 14, 2016. 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.
