Secretary of State James Brokenshire has said Bombardier jobs are “absolutely vital to the Northern Ireland economy”.
He was speaking after meeting with the company’s chief executive Michael Ryan and the union Unite on Monday.
Four thousand workers are employed by the Canadian aerospace company in Belfast, where the wings for the C-Series Jet are made.
Mr Brokenshire said he wanted to underline the UK Government’s support for Bombardier in its ongoing dispute with American rival Boeing.
“Today's visit provides assurance on the UK Government's continuing commitment and efforts, to protect jobs and the livelihoods of so many people across Northern Ireland and discuss how we can continue to work together to resolve this very serious issue,” he said.
“There is a compelling requirement for all in politics, in business and across the community to stand as one on this issue.
“The UK Government's commitment has been clear from the outset, with the prime minister, business secretary and other cabinet colleagues working tirelessly to bring this matter to a satisfactory conclusion.”
“We will continue to work with the senior management at Bombardier, the trade unions and the workforce as well as with the Canadian and US Governments to find a resolution.
"I hope this fight can be boosted by getting Stormont back up and running. I remain hopeful a political deal can be done and I again call on the parties to resolve differences and work together for everyone in Northern Ireland.”
Over the weekend, James Brokenshire said action by the Boeing against Bombardier was “unjustified and unwarranted".
