China should brace against criticisms, as world's movers and shakers meet later this week in Davos, Switzerland for the 45th Annual World Economic Forum.

China has been highly criticized by foreign business groups over its alleged discrimination against non-Chinese companies.

China's Premier Li Keqiang will make a rare appearance, along with 40 other heads of state. Li is expected to deliver a speech to boost the confidence of foreign business groups, which had been facing the brunt of China's antitrust laws.

Experts on modern Chinese politics urged China to use the gathering as a platform to reassure the international community that China is still open for business.

In an editorial at L.A. Times, Rhodes scholar Julian Gewirtz suggested Beijing to be transparent with its procedures and data to boost credibility of its government.

China is also urged to explain to companies legal rights of targeted firms, and announce concrete ideas on how it can replace its current aggressive approach to a more credible system of enforcement.

Gewirtz also calls on China to allow companies to consult regulators to reduce further uncertainty. This could mean adopting a system similar to the U.S. Foreign Corrupt Practices Act's Opinion Procedure, which allows companies to clarify with officials government's enforcement policies.

Gewirtz's final suggestion is for China to enforce same regulations for both foreign and domestic companies. Many foreign companies have complained against China's uneven playing field, with its anti-monopoly law in place targeting foreign firms, while providing free passes for huge state-owned companies.

It will be the first time in five years a Chinese leader is attending the Davos forum. Li attended the 2010 annual gathering as vice-premier.

The annual gathering themed "The New Global Context," will run from Jan 21-24 , where world leaders are expected to explore solutions to worlds' greatest challenges.
