Glencore International PLC, the world's largest publicly traded commodities supplier, cleared the final regulatory hurdle in its $30 billion takeover of Xstrata Plc after gaining approval from Chinese authorities, according to three people with knowledge of the matter.

China's Ministry of Commerce allowed the takeover to proceed, with an announcement expected on Tuesday or Wednesday, the people said. The deal won agreement from South Africa's antitrust regulator in January and the European Union in November.
