BERLIN (Reuters) -Volkswagen is holding "fair" and "constructive" talks with the United States government on tariffs and wants to make further investments in the country, CEO Oliver Blume told German newspaper Sueddeutsche Zeitung.

"So far, we have had absolutely fair, constructive discussions," Blume told the newspaper in an interview published on Friday. "I was in Washington myself and we have been in regular dialogue ever since."

Blume, who also leads Porsche AG as CEO, said Volkswagen's main contact in Washington was U.S. Commerce Secretary Howard Lutnick, adding he had agreed to keep any details of the discussions confidential.

Sources told Reuters earlier this week that Germany's carmakers, including Volkswagen, were in talks with Washington over a possible import tariff deal, seeking to use their U.S. investments and exports as leverage to soften any blow.

Asked what Blume was offering in the talks, he said: "The Volkswagen Group wants to invest further in the USA. We have a growth strategy."

Blume said the Volkswagen Group already employed over 20,000 people directly and over 55,000 people indirectly in the United States, also singling out a $5.8 billion investment in U.S. company Rivian .

"We would build on this with further, massive investments," Blume said, without elaborating.
