European Union finance ministers will tell a G20 meeting this week that they will resist protectionism and that regulation introduced after the 2008 financial crisis must be kept in place.
A document which appears aimed at the US, sets out the position of all European delegations to the G20 gathering of ministers and central bankers in Baden-Baden in Germany on March 17-18.
"We reaffirm our commitment to keep the global economy open, resist protectionism and keep global economic cooperation on track," the paper, seen by Reuters, said.
An early draft communique for the G20 meeting suggested on March 7 that the world's financial leaders might no longer explicitly reject protectionism, breaking with a decade-old tradition.
Instead, following the change of administration in Washington, they might promise only to keep an "open and fair international trading system".
This wording some officials see as a way to accommodate the protectionist views of President Donald Trump.
The draft communique, however, could change substantially, following discussions at the meeting, G20 officials said.
International Monetary Fund chief economist Maurice Obstfeld and a senior German government official both said they expected the G20 to debate a proposed overhaul of the US tax code which would favour exports over imports.
"It'll be discussed. There will be a lot of questions among the finance ministers," Obstfeld said.
He added that the proposed border adjustment tax (BAT) would have spillover effects because it would strengthen the dollar.
Emerging economies like Saudi Arabia would be most affected, Obstfeld said.
The German G20 presidency expects constructive discussions and a "good agreement" at Baden-Baden, the senior German government official said, speaking on condition of anonymity.
Asked if the US tax dispute would overshadow the meeting, the official said: "There is no reason to be pessimistic about relations with the US, but there will be the need to discuss issues like tax policy".
Germany wants the G20 meeting to focus on strengthening economic resilience, mastering challenges of digitisation and helping African countries with investment programmes.
Trump has already formally withdrawn the US from the Trans-Pacific Partnership trade deal, distancing America from its Asian allies, and vowed to renegotiate a free-trade deal with Canada and Mexico.
The president has also threatened foreign companies with a border tax on products imported into the US market, saying such a levy would help create more jobs on American soil.
German Chancellor Angela Merkel will discuss trade and other pressing issues with Trump during talks in Washington today.
The European Union ministers' document also appears to argue against Trump's plans to roll back US legislation, called the Dodd-Frank Act, introduced to prevent another financial crisis like that one in 2008.
"Avoiding a rollback in the financial regulation agenda is necessary," the document said.
European Commission Vice President Valdis Dombrovskis said in February that while the US had every right to redefine its national interest, Europe was entitled to say that international cooperation on financial governance was in everyone's interest.
"We are sensitive to talk of unpicking financial legislation, which applies carefully negotiated international standards and rules," Dombrovskis said.
"It is difficult not to notice when the chair of the Federal Reserve is criticised for her approach to negotiating international rules and standards, or when an American president talks about 'doing a big number' on Dodd-Frank."
Bundesbank President Jens Weidmann, who co-chairs the G20 meeting with German Finance Minister Wolfgang Schaeuble, has said it would be a mistake to roll back international regulation that has forced banks to build bigger buffers.
The US tax plans and the review of banking rules will also be discussed by Schaeuble and his US counterpart, Steve Mnuchin, during a bilateral meeting in Berlin on Thursday before the broader G20 meeting on Friday and Saturday.
