* Chinese regulators differ over bid for GM's Hummer
* Decision could come as early as this month
* NDRC approval critical to lowering costs

HONG KONG/DETROIT, July 14 (Reuters) - As a decision looms over GM's controversial plan to sell its Hummer unit to a little-known Chinese firm, the two Chinese regulators in charge of approving the deal seem to be on opposite sides of the road.
The National Development and Reform Commission (NDRC), China's top economic planner, generally opposes a deal that captured global headlines last month, due partly to environmental concerns around the gas-guzzling Hummer and the vague plans that suitor Sichuan Tengzhong Heavy Industrial Machinery has for the brand, a politically connected source said.
But the influential Ministry of Commerce (Mofcom) seems more supportive of Tengzhong, the Chinese machinery maker that launched its surprise bid for Hummer last month, the source said, adding a decision could come as early as the end of this month.
The divergent paths are unusual for Beijing, where regulators often speak with a single voice that comes from the top. Failure to reach consensus could delay a deal or even see it rejected.
In a similar recent case, eleventh-hour, high-level objections killed off Coca Cola's planned purchase of leading Chinese juice maker Huiyuan, even after Mofcom was initially positive on the deal.
The Sichuan government has shown strong support for Tengzhong's Hummer buy and is lobbying both Mofcom and NDRC to get it passed, the source said.
The NDRC did not respond to calls seeking comment, while a Mofcom spokesman said he had heard of no changes to the process, which the companies have said they expect to be completed in the third quarter.
The NDRC's blessing is crucial if Tengzhong wants to move any of Hummer's manufacturing to China, as it oversees such investments. At the same time, simple approval of the deal must come from Mofcom, said Zhang Xin, an analyst at Guotai Junan Securities in Shanghai.
"If Tengzhong wants to set up a factory in China after acquiring the brand to lower costs, this would require NDRC approval," he said. "But based on the current situation, this looks nearly impossible."
The deal's announcement in June prompted a flurry of editorials in China's state-run media, many questioning the logic of a struggling U.S. icon being acquired by a company with no experience making cars or running an international company.
But in the midst of the generally negative views, Mofcom seemed to take a more neutral stance, saying the bid was normal behaviour for a company seeking to take advantage of the global downturn to broaden its horizons.
A spokeswoman from the public relations company representing Tengzhong said the company had no news from Chinese regulators, including anything about different agencies having opposing views on the deal.
GM CEO Fritz Henderson told reporters last week the deal was going through the regulatory approval process and he was optimistic, though he gave no timeframe.
"We're supporting the sale process but ultimately the purchaser's approval process needs to go forward and be approved and I don't control that, but our expectation is that this deal can be done."
