Global law firm Baker & McKenzie is in the spotlight this week following a report by the Wall Street Journal that it won work from China National Offshore Oil Corporation (CNOOC) following inappropriate conduct by one of the company’s in-house lawyers.

The report says the state-owned oil giant’s then legal director, Karen Kang Xin, who is married to Bakers’ chief representative in Beijing Stanley Jia, acted in breach of Chinese regulations and company policy by going on trips paid for by the firm and then helping it to win mandates.
