US power technology group AMSC has agreed a settlement of all outstanding commercial disputes with Chinese OEM Sinovel, as one of the highest-profile legal clashes in the history of the wind industry draws to a close.

Sinovel will pay AMSC the equivalent of $57.5m over two installments, the first on 5 July and the second within 10 months of a US court sentencing the Chinese group on criminal charges of trade secrets theft.
