Kazakhstan says freeze lifted on $22 billion in oil fund assets

The assets held by the fund's custodian, Bank of New York Mellon , were frozen last October after a lawsuit by Moldovan businessman Anatolie Stati who seeks to enforce a $500 million arbitration ruling against the Astana government.

The freeze had shocked the oil-exporting nation and the sovereign fund industry, partly because of the disproportion between the size of the claim and that of the frozen assets.

Stati, his son Gabriel and their companies were investors in Kazakhstan's oil and gas industry. They say they have been subjected to harassment from the state aimed at forcing them to sell their investments cheaply.

Kazakhstan denies the allegations, but Anatolie and Gabriel Stati and two of their companies – Ascom Group S.A. and Terra Raf Trans Traiding Ltd, have won an international arbitration award of around $500 million against the government.

Kazakhstan has refused to pay, accusing Stati of using fraudulent means to secure a favourable arbitration ruling and filing lawsuits against him.

The Justice Ministry said in a statement on Wednesday it was also seeking the reversal of a court ruling in Belgium which had frozen some Kazakh assets.
