Britain’s promise to strike bilateral trade deals could put Europe in a “very unfavorable position,” the Hungarian foreign minister said Monday.

“We are interested in a fair Brexit, we are interested in a solution which will ensure a strong and tight mutually beneficial economic cooperation,” Péter Szijjártó told reporters during a break in a meeting of EU foreign ministers in Brussels.

However, he warned that without cooperation with Britain the rest of the Continent could find itself “in a very, very unfavorable position" particularly given the likelihood of the U.S. and the U.K. agreeing some kind of economic cooperation.

In interviews with the Times and Bild, President-elect Donald Trump said his administration would "work very hard to get [a trade deal] done quickly and done properly," reversing the position of Barack Obama's administration which made it clear that such a deal was not a priority.

Szijjártó’s concern does not only involve a potential bilateral deal with the U.S.

“I have seen the announcement, after the last visit of [British Foreign Secretary] Boris Johnson to Turkey, that their intention is to sign a jumbo-type free trade agreement with Turkey," Szijjártó said. "So if the U.K. will be able to sign economic and trade agreements with many serious actors of the world economy, and [at the same time] if the EU is not able to build this kind of cooperation with the U.K., then is going to be a very unfavorable position for us."

However, any bilateral deal can only be signed once the U.K. leaves the bloc, Federica Mogherini, the EU's foreign policy chief, stressed Monday.

“It is absolutely clear on the European Union side that as long as a country is a member state of the European Union, which is something the U.K. is at the moment ... there are no bilateral negotiations on any trade agreement with third parties,” she said during a press conference at end of the foreign ministers' meeting, saying this applies to all member countries "until the very last day.”

This is something “that we all share, including the United Kingdom,” she said, adding that she had discussed the issue with Johnson “and he was agreeing with me."
