China's Chengdong Investment Corporation has announced it now owns a 12.5 percent stake in Uralkali, says Vedomosti.

      The deal was made possible due to an earlier bond issue which gave their owners to convert them into shares in 2014.

      Why the conversion was made before 2014 has not been disclosed.

      The unit of China's sovereign wealth fund has now the right to one seat in the board of directors.
