Goodrich will have to divest its electrical power generation and transmission systems businesses and should sell 60 percent of Aerolec, a joint venture with Thales Avionics, within six months, China's Commerce Ministry said on its website.

The European Commission is also currently examining the deal, UTC's biggest in a decade, with which it aims to build critical mass in new aircraft technology and plane services to take advantage of a recovery in civil aviation demand.

UTC has offered to sell undisclosed assets to secure EU regulatory approval of the takeover.

The Commission, which has set an August 31 deadline for a decision on the deal, is expected to discuss the proposed concessions with rivals and customers of United Tech and Goodrich.

United Technologies' products include Pratt & Whitney engines and Sikorsky helicopters and the company is a top player in aircraft landing gear.
