PARIS/BRUSSELS (Reuters) - France cast serious doubt on Tuesday on the prospects of an EU free trade deal with the United States, adding to opposition within Germany and growing scepticism among Americans.

Washington and Brussels are officially committed to sealing the Transatlantic Trade and Investment Partnership (TTIP) before U.S. President Barack Obama leaves office in January, but their chances of doing so are being eroded by approaching elections on both sides of the Atlantic and Britain’s vote in June to leave the European Union.

“Everything is moving. In this situation it’s just not going to happen,” said Peter van Ham, senior research fellow at Dutch think tank Clingendael and author of a paper on Tuesday called “TTIP is dead, long live transatlantic trade”.

French Trade Minister Matthias Fekl said he would request a halt to TTIP talks at next month’s EU trade ministers’ meeting in Bratislava after German Economy Minister Sigmar Gabriel declared at the weekend that talks were “de facto dead”.

Observers say both are responding to public mistrust of a deal that critics say would lower environmental and food standards and allow foreign multinationals to challenge government policies.

Stop TTIP campaigns have been particularly vocal in Germany and Austria, which supporters of TTIP say are among the countries most likely to benefit from increased U.S. trade.

In the United States, Obama has promoted the accord, saying it would fuel growth. But the public mood is turning increasingly negative, with Republican presidential candidate Donald Trump making attacks on international trade deals a cornerstone of his campaign, saying they have cost U.S. jobs.

His opponent, Democratic nominee Hillary Clinton, has also stepped back from her previous support for free trade when she was U.S. Secretary of State, and has questioned whether trade deals hold down U.S. wages.

FRENCH, GERMAN ELECTIONS LOOM

German Foreign Minister Frank-Walter Steinmeier, of Gabriel’s Social Democratic Party (SPD), urged diplomats and business chiefs on Tuesday to counter anti-globalization sentiments that are fuelling opposition to free trade deals.

Ahead of elections in France and Germany next year, politicians are keenly aware that TTIP is not a vote winner.

The Bertelsmann Foundation poll showed only 17 percent of Germans saw TTIP as a good thing in April, down from 55 percent two years earlier.

“There may be an economic rationale, but everyone is scrapping for votes and you lose votes if you support TTIP,” Van Ham said, adding that any credit from potential free trade gains would be two to three years away.

Supporters say TTIP could boost each economy by $100 billion, creating jobs at a time of economic uncertainty as growth and consumption slow in China and emerging markets. EU leaders backed TTIP talks at a summit in June.

Speaking to reporters in Washington, White House spokesman Josh Earnest admitted “significant aspects” of the deal were unresolved, but said U.S. Trade Representative Michael Froman would travel to Europe in an effort to push the talks forward.

“I anticipate that when he travels to Europe in mid-September that they’ll be engaged in substantive discussions and hopefully will be able to make some additional progress,” Earnest said.

Three years of negotiations have failed to resolve multiple differences, however, including over public procurement and rules to protect foods from particular regions, such as Parma ham, which the EU wants, and greater access to services and for its agricultural products, as demanded by the United States.

“Practically there’s no real change. It’s been stuck for the better part of two years,” said Hosuk Lee-Makiyama, director of Brussels-based think tank ECIPE.

BREXIT QUESTION

EU trade chief Cecelia Malmstrom told journalists negotiations had not failed and that many EU countries had said they still backed TTIP.

They included Italy, whose trade and industry minister said it was essential for Italian exporters that the negotiations bore fruit.

Germany’s Gabriel is the chairman of the SPD who share power with Chancellor Angela Merkel’s conservatives. Merkel backs the talks and her spokesman insisted on Monday that they should continue.

Malmstrom added that it made no sense to suspend talks in September because the two sides could still make advances in regulatory cooperation, agreeing standards that are important to industries such as the auto sector, and that could be picked up by Obama’s successor even if a deal was not sealed this year.

“The more work we have done, the easier it is to resume,” she said before a planned video conference with Froman.

Froman has said Britain’s EU exit will affect TTIP because Britain consumes about a quarter of U.S. exports to the bloc.

Trade analysts say that Washington may be preparing for the end of trade talks, which typically conclude with each side holding the other responsible for failure.

President Francois Hollande told ambassadors on Tuesday that talks were “bogged down” and “unbalanced” and it was an illusion to imagine that a deal could be sealed during Obama’s term.

“Very soon you end in a blame game,” said Lee-Makiyama. “But trade negotiations never really die. They just go into a stock-taking phase.”
