The ministry declined to comment to reporters on the draft rules.
Michael Dunne, of Dunne Automotive consultants in Hong Kong, has had more than two decades of experience in the Chinese market that is now the world's largest.
He suggests that China's bureaucrats may not be much interested in what the rest of the world's auto industry thinks.
He noted that the China Association of Automotive Manufacturers, that country's trade group for its automakers, is not a signatory to the letter calling the rules "impossible."
Of 28 million vehicles of all types sold last year in China, he noted, 96 percent were built within the country.
China has tested the limits of its regulatory power for 33 years, Dunne said, since Beijing Jeep became the first joint-venture assembly plant as China loosened rules on production.

Then it had no power, and could not force that venture to export vehicles and bring in hard currency. "Today, the tables have turned," Dunne wrote to Green Car Reports.
"If certain global carmakers cannot or will not make the new energy vehicle quotas, demand could be met by the wave of up and coming Chinese electric-car makers."
"How long before rattled global automakers, more dependent than ever on China's market, start learning a proper kow-tow?"

Postscript: Dunne added in a later note, "Kow tow is from the Chinese ke tou which means 'knock head' (against the ground). Or, for foreign automakers, against the wall."
