Sinn Féin's Stormont leader has said there is no basis for power-sharing negotiations to resume unless the Irish and British governments commit to delivering on "rights" based issues.
Michelle O'Neill said the British government had not produced any firm proposals to move the process forward.
She was speaking after a meeting with the Secretary of State James Brokenshire.
DUP leader Arlene Foster told her party's weekend conference that she still believed a devolved administration at Stormont was the best form of government for Northern Ireland.
Power-sharing collapsed last January when the relationship between the two main parties broke down.
Ms O’Neill said: "When the last phase of talks ended, we made it very clear that the issue of rights was not going to go away.
"We have today had a meeting with the British government, with James Brokenshire.
"He did not put any process on the table that would allow for the delivery of rights or a process that we could sign up to.
"So as we stand here today, the onus remains on the British government and indeed the Dublin government to deliver the rights based issues; rights that are available to citizens elsewhere on these islands and in that case, that would pave the way for the Executive to be restored.
"What we can't do is go round and round a hamster wheel in endless talks."
Her comments appear to have punctured British Prime Minister Theresa May's hope that negotiations could resume this week.
DUP MLA Simon Hamilton accused Sinn Fein of "checking out" of politics in Northern Ireland.
He said: "Sinn Féin brought Stormont down almost a year ago. Now they're refusing to re-enter talks aimed at re-establishing the executive.
"Sinn Fein voters, as much as voters for any party, need a government up and running again to deal with issues in health, in housing, in education and in the economy.
"One would be forgiven for coming to the conclusion that Sinn Féin have 'checked out' of politics in Northern Ireland and are now only interested in the politics of the Irish Republic."
Power-sharing collapsed in January when Sinn Féin pulled out of the executive with the DUP, in protest at allegations of how it had handled a renewable energy scheme.
Since then, both parties have entered numerous rounds of talks aimed at restoring the executive. However, the parties have been unable to reach agreement on a number of issues related to language and culture.
Sinn Féin has called for a stand-alone Irish language act, but the DUP has said it will only agree to a cross-community language bill with provisions for Ulster Scots.
Earlier this month, a budget was passed at Westminster to ensure local government departments did not run out of money in the absence of a devolved Assembly to pass the legislation.
Mr Brokenshire has insisted that passing the budget is not tantamount to direct rule, and urged the parties to continue talks in a bid to reach an agreement.
