The Association of Investment Management and Research (AIMR) will not hesitate to withdraw from China if it cannot enforce its rules on members there, according to its president and chief executive Thomas Bowman. 'I've made it clear that while our organisation welcomed [mainland investment professionals], if we failed to enforce our rules on our members because of official intervention, we reserve the right to stop doing business there,' said Mr Bowman, who heads the world's largest investment analyst group. The AIMR, with more than 67,000 members worldwide, is a non-profit organisation which administers the Chartered Financial Analyst exams. Mr Bowman, in Hong Kong for the AIMR's global conference, said he was concerned over the lack of transparency in mainland financial markets. He said maintaining the AIMR's mainland members' ethical standards could pose an unprecedented challenge for the group. 'It would be difficult for us to investigate cases of unethical behaviour involving our members if their employers or the government, for whatever reasons, were preventing us from doing our job,' Mr Bowman said.
