Sinn Féin met The British Prime Minister Boris Johnson on Monday.
Any move to unilaterally override parts of the protocol would put Northern Ireland in a “very dangerous place” due to potential retaliation from the EU.
Speaking on RTE's morning Ireland Michelle O’Neill told the potential action “furthers instability politically”.
“I don’t think anybody could trust the word of Brandon Lewis or Boris Johnson,” she insisted.
“Essentially what you can put it down to is they intend to go down this route of legislating to override an international agreement. That is not the way to conduct business," she added
Sinn Fein vice president Michelle O’Neill, said UK Foreign Secretary Liz Truss' plans would potentially see Northern Ireland “caught out in the middle of a game of chicken”.
Sinn Fein were one of the five parties who met with British Prime Minister Boris Johnson during his visit to Belfast on Monday.
Ahead of his meeting with the parties and writing in the Belfast Telegraph, the Prime Minister said “there will be a necessity to act” if the EU did not change its position on the protocol.
"The Prime Minister is absolutely right"
