According to Sina Finance on January 9, Boris Johnson and Ursula von Delaine's views on the arrangements for relations between the two sides after Brexit have drawn a red line of opposition, and the conflict between the two sides has begun, which is bound to make this negotiation more difficult than the difficult confrontation between Britain to leave the European Union.

This is the first face-to-face meeting between the two men since Von der Lane became president of the European Commission on December 1. British Prime Minister Johnson's office said Johnson stressed that Britain would not extend the post-Brexit transition period beyond the end of this year and that he wanted to reach a Canadian-style free trade agreement.

Crucially, Johnson said any future partnership should not dock in any way with EU rules and standards, or be subject to the jurisdiction of the European Court of Justice. Earlier, Mr von der Lane stated the EU's position, saying it was "impossible" to reach a comprehensive agreement by Mr Johnson's year-end deadline, adding that every decision would be accompanied by a "compromise".

"without the free movement of people, there can be no free movement of capital, goods and services," von der Lane told an audience at the London School of Economics. "the highest quality access to the world's largest single market cannot be achieved without a level playing field in the areas of environment, labour, taxation and state assistance."

There have been disputes over Britain's exit from the European Union over the past three years, and their comments indicate that the negotiations will still be fraught with problems in the coming year. With only 11 months left to finalize a partnership agreement before the transition period ends at the end of December, there is a potential risk that trade rules could change abruptly by early 2021.

Von der Lane said time was "very tight". "it's not a matter of success or failure," she said. "it's a matter of priority."

Johnson's wish is to negotiate according to the number of free trade agreements already reached between the European Union and Canada, but his timetable makes that goal problematic. According to the European Union, the Canadian agreement is its most ambitious trade deal ever, but it took seven years to negotiate. Under this agreement, 98% of the goods traded between the two sides are duty-free, and there is also some convergence of trade in services and certain standards.

At present, Johnson told von der Lane that his "top priority" is to make the "withdrawal agreement" into law, which will take effect on January 31. On Wednesday, the second day of a three-day debate on the bill in the House of Commons, Johnson's Conservative Party won 80 seats in last month's election, successfully defeating several attempts to change the bill.

Once Britain formally leaves the European Union, negotiations on future trade relations will officially begin, Johnson told von der Lane that he hopes to start negotiations "as soon as possible after January 31".
