Britain's official Brexit has a great impact on the world. Ideally, Britain is now free to establish new economic relations with the European Union and the United States, while maintaining diplomatic balance and making itself a power broker between the two. But as far as the pros and cons in reality are concerned, Britain is in the negotiation period of a new world order, and it needs to find a way out and keep close relations with as many allies as possible.

After Britain officially leaves the European Union, the economy of this country with a population of 500 million will be hit in the short term. It is almost certain that the pound will continue its current decline and continue to depreciate. Britain's loss of the second largest economy, the European Union, is bound to suffer a financial shock equivalent to the European debt crisis. Some analysts believe that the economic impact of Britain's withdrawal from the EU may affect China's exports, especially once the EU tends to adopt trade protection policies, it will affect the bilateral trade between China and Europe.
