Why did Ireland refuse to redraw its border after Britain left the EU?

On September 8th, local time on Friday (8th), Ireland rejected Britain's proposal to draw a border with Ireland after Britain left the EU, calling it "unconvincing". The Irish Foreign Minister said that drawing a practical boundary between Ireland and Northern Ireland may endanger peace.

It is reported that the border between Ireland * * * and Britain's Northern Ireland is currently open to the free flow of goods, which is within the EU, but after Britain leaves the EU, the border here must comply with EU customs regulations. According to the report, the delineation of the physical border may cause security concerns. Twenty years ago, Britain and Ireland signed a peace agreement to end the long-term civil war in Northern Ireland, and the army and police no longer set up checkpoints.

According to reports, Britain proposed that after Britain left the EU, the two countries should adopt an "invisible border" without setting up border posts or conducting immigration review, but Britain did not explicitly propose how the customs border between Northern Ireland and Ireland should operate.

Banier, the EU's British exit negotiator, said on Thursday that Britain's proposal would gradually undermine the EU's single market system. He believes that Britain's attempt to test the border customs regulations with the EU through this case "actually wants the EU to suspend the application of its laws" and "this will not happen".

Simon Coveney, Irish Foreign Minister, said on Friday local time that the actual border between Ireland and Northern Ireland may endanger decades of peace talks after Britain leaves the European Union, and the British solution has not been sufficient so far.

Coveney said, "We can't demarcate the actual border on the island of Ireland again. This will create obstacles between ethnic groups, cause tension, and even undermine the peace process that it took us 30 years to establish. " Regarding the British proposal, Kovney said, "The problem is that the British solution has not convinced us so far."

According to the report, after Britain left the European Union, the question of how to charge between Ireland and Northern Ireland was very sensitive, because Northern Ireland had been in bloody conflict for decades on whether it belonged to Britain or Ireland.
