What specific action did Kazakhstan take against the Kashagan oilfield operator, and what is the stated reason?

Kazakhstan froze the property and transport assets of the North Caspian Operating Company (NCOC), the operator of the Kashagan oilfield, on July 21 due to its non-payment of a nearly $5 billion environmental fine. The justice ministry's database confirmed the freeze but did not specify which assets or vehicles were affected.

What is the legal and financial status of the $5 billion environmental fine imposed on NCOC?

Kazakhstan has imposed a 2.3 trillion tenge ($4.84 billion) environmental fine on NCOC for alleged breaches of sulphur storage limits and has warned the company's head of possible criminal prosecution; however, NCOC and its contractors reject both the fine and the underlying allegations, and the dispute is currently being adjudicated in international arbitration.
