The China National Offshore Oil Company Ltd. terminated its relationship with Baker & McKenzie and demoted one of the state-owned oil and gas giant’s in-house counsel, alleging that she had engaged in a conflict of interest by steering work to her husband, who is head of the firm’s Beijing office, according to a report this week by The Wall Street Journal.

Baker & McKenzie would not comment on the assertion that its relationship with Beijing-based CNOOC had concluded. The firm told The Am Law Daily that it had done nothing wrong.
