Turquoise Hill Resources said on Tuesday the Oyu Tolgoi mine in Mongolia had partially resumed shipments to China, after the Canadian miner declared force majeure on some Chinese contracts last month due to COVID-19-led curbs.

The company is evaluating multiple contingencies, including an alternative shipping route via Mongolia’s capital city of Ulaanbaatar, to deal with the force majeure, which refers to unexpected external factors that prevent a party from meeting contract obligations.
