"LUKoil has unilaterally almost halved oil coke supplies to RusAl's largest aluminum plants since April 2008, failing to meet its obligations under long-term contracts," RusAl said.
Under a contract signed between the two Russian companies in 2006, LUKoil undertook to supply oil coke to RusAl until April 2011 for the production of anode paste and anodes. However, in April, LUKoil curtailed shipments while selling oil coke to other customers. At the same time, RusAl has honored its obligations, the aluminum giant said.
"As LUKoil disrupted its contractual obligations and its representatives are not willing to enter into a constructive dialogue, UC RusAl believes that the only possible way to resolve the situation and ensure the contract is fulfilled in full is to take legal action," the aluminum giant said.
LUKoil has not yet commented on RusAl's statement.
