Mae Llywodraeth Cymru o'r farn y dylai Llywodraeth y DU aildrafod â’r Comisiwn Ewropeaidd i geisio datrysiad i faterion sy'n ymwneud â Phrotocol Gogledd Iwerddon. Mae o’r farn hefyd, os bydd Llywodraeth y DU yn bwrw ymlaen â'r Bil, y byddai risg o ddwysáu mesurau gan yr Undeb Ewropeaidd ynghyd â rhyfel masnach o bosibl. Nid yw hyn er lles busnesau a phobl Cymru sy'n dibynnu ar fasnach â’r UE. Ar adeg pan fo pobl eisoes yn wynebu caledi oherwydd effeithiau'r argyfwng costau byw, gallai gweithredoedd Llywodraeth y DU niweidio economi Cymru.
The Welsh Government believes that the UK Government should return to discussions with the European Commission to seek a solution for issues relating to the Northern Ireland Protocol and that if the UK Government proceeds with the Bill it would risk a further escalation of measures by the European Union and, potentially, a trade war. This is not in the best interests of the businesses and people of Wales who depend on trade with the EU. At a time when hardship is already being experienced because of the effects of the cost-of-living crisis, the UK Government’s actions could damage the Welsh economy.
