Political instability in Northern Ireland has not stopped businesses from flocking to a major investment conference in Belfast, Northern Ireland Secretary Chris Heaton-Harris has said.
He also predicted the Windsor Framework would make a "big difference" to trade in the region.
Around 200 investors from across the world, including the US, Europe, the Middle East and Asia Pacific, are attending the summit at the ICC.
There have already been a series of jobs and funding announcements, including the creation of 1,000 new jobs by professional services firm EY over the next five years.
Opening the event, Mr Heaton-Harris told delegates that Northern Ireland has "enormous economic potential and is full of the talent and expertise required by the sectors of the future to succeed and to thrive".
Political leaders were among the crowd which filled the seats and standing room at the back as Mr Heaton-Harris said he expects progress around Stormont "very soon".
He said: "I had hoped by now that we would have an executive back up and running, for potential investors travelling here today to be met by ministers from Northern Ireland and discuss their ideas, sadly this has proved not to be the case.
"But my team and I have worked intensively with the DUP, and indeed all the main Northern Ireland political parties across the summer, and I'm genuinely hopeful that progress will be unlocked very, very soon.
"I know it will require courage on all sides to prioritise reconciliation and prosperity over division, but I know this can be done because it was done in spades 25 years ago to deliver the foundation of peace and prosperity here in Northern Ireland."

The summit was first announced during events to mark the 25th anniversary of the Good Friday Agreement.
However, it is taking place while the devolved power-sharing institutions at Stormont remain dormant, with the DUP maintaining its protest over post-Brexit trading arrangements.
But speaking to reporters, Mr Heaton-Harris predicted the Windsor Framework, agreed by the UK and EU to deal with trading issues caused by the Northern Ireland Protocol, would have a positive effect on trade.
He said: "About 500 of the tangible benefits are sat next door, because lots of people are in that room because they see benefits for their businesses to invest in Northern Ireland because of what the Windsor Framework is bringing.
"On October 1 the first phase of the Windsor Framework comes in and we will see a big difference in how trade flows, and indeed goods coming into this country."
Speaking about the event taking place with no devolved government in Northern Ireland, Mr Heaton-Harris said: "It is not the most ideal situation.
"However, all these people are here given that situation. They all know about it, they all know that the UK government is doing everything it can to get over that particular hump.
"I also think what they are seeing is a huge government presence to demonstrate that, working together, we can bring lots of opportunities for businesses here.
"I think, based on the buzz around the place, this will work, and work well."
Business and Trade Secretary Kemi Badenoch said all parties in Northern Ireland are represented at the event.
She said: "What the UK government is doing is bringing international investors to see what the opportunities are.
"We do have representatives from all parties in Northern Ireland here at the summit and we are working well together.
"At the moment, we can call it a success."
A number of industry-led sessions at the summit are focusing on advanced manufacturing and engineering, technology, financial and professional services, the green economy, and the life and health sciences sector.
Nineteen companies from across Northern Ireland will also exhibit to global investors, including Derry-based Respiratory Analytics, Collins Aerospace in Kilkeel, and Ballymena-based Wrightbus.
Sinn Féin Stormont leader Michelle O'Neill said the opportunities provided by the Northern Ireland Investment Summit cannot be missed.
Speaking at the event in Belfast, she said: "The DUP need to end their blockade (of Stormont), they need to get into the executive with the rest of us and take these opportunities that we have.
"There is tremendous opportunity here. We have to capitalise on access to both markets.
"We have an attentive international audience.
"These opportunities shouldn't be missed."
Northern Ireland's political difficulties do not have to be a barrier to investment, US special envoy Joe Kennedy III has said.
It is Mr Kennedy's third visit to Northern Ireland since his appointment, having previously been in Belfast during the visit by President Joe Biden and during events to mark the 25th anniversary of the Good Friday Agreement.
Mr Kennedy said that Northern Ireland was not alone in facing a difficult political landscape.
He said: "When it comes to politics, Northern Ireland isn't the only place which has challenging politics these days.
"Politics is hard, you have to work through it, the people of Northern Ireland, this place is ripe for investment, ripe for potential."
He added: "There is an enormously positive story to tell, there are opportunities here in Northern Ireland because of the people here in Northern Ireland, because of the investment we have already seen, because of the validation we have seen from the 1,200 international companies that do business here.
"That is a credit to the people of Northern Ireland.
"The opportunities because of the Windsor Framework I think are all the more attractive.
"A lot of credit goes to the British government and their counterparts in the EU for being able to reach that agreement."
