The most important thing that needs to be done as China deepens its economic reform is to have a truly unbiased rule of law, said Lady Lynn Forester de Rothschild, CEO of E.L. Rothschild Ltd, a privately funded family investment company.

"Rule of law will reduce the cost of doing business here because the cost of capital is lower where there is confidence in the legal and judicial system," said Lady de Rothschild on Saturday on the sidelines of the annual Sanya Forum presented by Caijing Magazine in the coastal city of Sanya, Hainan province.

"There would be much more investment with a more transparent rule of law across the society, and it's very good for the global situation because it would remove uncertainty…I believe China is moving towards that direction," she said.

E.L. Rothschild is a family-owned investment holding company established in 2003 by Lynn Forester de Rothschild and her husband Sir Evelyn de Rothschild, a British financier and a member of the Rothschild family.

Its global investments include the Economist Group, a multinational media company headquartered in London, IHS Towers, Africa's leading mobile telecommunications infrastructure provider, and FieldFresh Foods Private Limited, a provider of branded fresh fruits, vegetables and processed food products in India.

The company is looking for investment opportunities in China.

"I think the most positive factor for outside investors is the emphasis of the government on consumer consumption, moving the economy away from investment growth to consumption growth. That creates a great opportunity for consumer goods companies to expand here," she said.
