SARAJEVO: Serbia may soon decide to annul all contracts related to mining group Rio Tinto’s $2.4 billion lithium project in the country, Prime Minister Ana Brnabic said on Saturday, as green groups blocked roads across Serbia protesting against the plan. Rio Tinto wants to develop the mine near Loznica in the western Jadar valley, but the local municipality has already scrapped a plan to allocate land for it.

The development is part of Serbia’s efforts to bring in investment and boost economic growth. But environmentalists have staged protests and blocked roads to press authorities to end the project, which they say would cause irreparable damage to the area.

Rio has said any development would meet domestic and European Union environmental standards.

The protests have caused a political headache for the ruling coalition loyal to President Aleksandar Vucic ahead of April elections.

“We have neither brought them (Rio Tinto) in, nor have we made promises, nor have we done anything that the people did not know about,” Brnabic told television channel Pink, saying the government was close to accepting all requests from environmentalists.

“We have worked in a transparent way, we have listened to the people,” Brnabic said, adding the government needed to see how much it would have to pay out if the deal is annulled.
