MINSK, September 3 (RIA Novosti) – Interpol put Russian billionaire Suleiman Kerimov on a wanted list Monday, Belarusian television reported, citing the Interior Ministry. Kerimov is the biggest shareholder in fertilizer giant Uralkali, which is embroiled in a commercial battle with its Belarusian counterpart.

Minsk is seeking his detention, including through an international arrest warrant, on charges that carry a possible sentence of up to 10 years in prison, the Belarusian state news agency BelTA reported.

The arrest warrant is an escalation of the criminal case facing businessmen linked to Uralkali after the company’s CEO, Vladislav Baumgertner, was arrested last week in Minsk's airport following a reported invitation from Belarusian Prime Minister Mikhail Myasnikovich to attend an official meeting.

In July, Uralkali, the world's biggest potash producer, dissolved an international cartel with Belarusian potash giant Belaruskali, blaming Minsk for violating their cooperation agreement. The move sent shares in fertilizer producers tumbling worldwide and has precipitated a steady fall in fertilizer prices as consumers and traders anticipate a spike in competition for customers.

Kerimov, Russia’s 20th-richest person with a fortune of $7.1 billion according to Forbes magazine, is wanted for abuse of power and official authority, Belarus’ Investigative Committee said, BelTA reported. Like Baumgertner, the charges against Kerimov are linked to his involvement in the Belarus Potash Company, the trading firm jointly owned by Belaruskali and Uralkali through which all their potash exports were channeled prior to their split.

The chairman of Uralkali’s board of directors, Alexander Voloshin, last week described the arrest of Baumgertner as “outrageous” and the charges against him as “absurd.” Russian First Deputy Prime Minister Igor Shuvalov said last week that the situation around Baumgertner was “rather strange.”

President Vladimir Putin’s spokesman, Dmitry Peskov, said Monday that the charges against Kerimov, who is also a senator in Russia's upper house of parliament, needed to be fleshed out.

While Russia has consistently provided subsidized exports and cheap loans to Belarus, ruled by strongman leader Alexander Lukashenko, the two countries have a long history of quarreling over economic questions. Lukashenko said last year that unspecified “Russian oligarchs” had offered him a $5 billion bribe to sell Belaruskali.
