Sondhi expanded and diversified widely. He owned a hotel in China's Yunnan province, ran a cement factory in Vietnam, and set up a regional business conference company. Most of his investments were woven in a complex series of cross-shareholdings. Sondhi himself kept few direct holdings in any of the companies, but was ultimately in control through his ownership of holding companies like M Group and other holding companies registered in the British Virgin Islands. Such a structure minimized Sondhi's tax bill and provided maximum protection in case of financial difficulties.
