TUI's plans to sell Hapag-Lloyd to focus on tourism have triggered a campaign to keep the business in the northern German city of Hamburg.
TUI Chief Executive Michael Frenzel toured Asia last month to market the business, which analysts say could be worth up to 5 billion euros ($7.85 billion).
The paper said Woehrl was concerned about possible job losses if a foreign player buys Hapag-Lloyd, which is the world's fifth-biggest container shipping business.
"This would not be in the federal government's interest," Woehrl said, adding, however, that the government did not plan to take a stake in the shipper.
Hapag has 140 ships and generated six billion euros in sales last year.
Reuters reported last month that Singapore's Neptune Orient Lines, the world's eighth-biggest container shipping firm, was looking to raise $5-$7 billion in loans to help fund a bid for Hapag-Lloyd.
Shares in NOL fell to a 14-week low this week on what dealers said were renewed concerns that it might overpay in a bid for the German shipper.
