ASTANA, Oct 28 (Reuters) - Kazakhstan's authorities are

determining how to deal with Russian oil producer Lukoil's

stakes in projects and could make a decision soon, the

chairman of sovereign wealth fund Samruk Kazyna said on Tuesday.

Lukoil said on Monday it would sell its international

assets following sanctions over Ukraine announced last week by

the United States.

"The sanctions are being studied and their impact on

companies and the economy remains to be fully assessed," the

fund's chairman, Aidar Ryskulov, told reporters in Astana.

"I think we will take (a decision) in the near future, by

the end of this week," he added.

Lukoil's planned sale of assets is the most consequential

action so far by a Russian company in the wake of Western

sanctions over Russia's war in Ukraine, which started in

February 2022.

The Russian oil major is a stakeholder in Kazakhstan's

Tengiz and Karachaganak fields, as well as in the Caspian

Pipeline Consortium, which carries Kazakh oil to Russia's port

of Novorossiisk for export.
