A group of fund management firms and investment analysts have urged businesses to adopt policies regarding freedom of expression, in what is an indication of tension between human rights advocates and U.S. internet and technology companies - including Google, Yahoo and Microsoft - that are doing business in countries with repressive regimes, writes the New York Times. In a joint statement, 26 companies and organizations representing about $21 billion in assets affirmed their commitment to keep an eye on firms' relations with authoritarian regimes - and to introduce and support shareholder resolutions that support freedom of expression.
