Input: Consider Input: Trucks and cars began crossing the border into North Korea at exactly 08:00 (23:00 GMT Sunday).
More than 800 South Koreans were due to cross to the jointly-run centre for what is being called a trial restart.
The zone, just inside North Korea, is home to 123 South Korean factories that employ more than 50,000 North Koreans.
It is the last functioning inter-Korean joint project and a key source of revenue for Pyongyang.

The last time trucks queued up at the Kaesong crossing point, five months ago, the border with North Korea remained resolutely closed.  This time, shortly after 08:00, the long line of vehicles began moving through, on their way to the newly-reopened industrial complex.
More than 800 South Koreans were due to cross over into Kaesong on Monday, to restart operations at around half the factories there.
The resurrection of the complex is the result of weeks of tough negotiations between the two sides, and those discussions are still not finalised.  Among those heading across the border today were a team of negotiators, tasked with hammering out the details for how the complex would look in future.
High on their agenda is the subject of internet and mobile phone access for the site - contentious issues for the North, but key if foreign investors are to be wooed to the complex as a stabilising influence.
After a five-month suspension of the complex, attracting foreign companies has perhaps become a little harder.  And even South Korea remains wary, calling Monday's operation a "trial run", not a formal and permanent re-opening of Kaesong.
But Kaesong remains, to many here, the "canary in the mine" of inter-Korean relations, and the agreement to resume operations there paved the way for further signs of a thaw between the two Koreas: the restoration of a military hotline, and a planned reunion of families separated by the Korean War.
Its commercial image may be tarnished, but Kaesong's importance as a political symbol here remains.
But the North withdrew all of its workers in April, as ties between the two Koreas deteriorated in the wake of Pyongyang's 12 February nuclear test.
Reopening the complex has taken months of negotiation.
South Korea's Unification Ministry said a total of 820 managers and workers planned to cross into the complex on Monday, with 400 to stay there overnight.
They will be inspecting production facilities to assess how quickly a full restart can be implemented after  five months of inactivity.
The restart is being described as a trial but more than half of the South Korean companies had asked North Korean employees to report for work, the ministry said.
Negotiations on resuming operations at the complex faltered for weeks on South Korea's insistence that safeguards must be in place to prevent any future unilateral shut-down of the site by North Korea.
But the two sides have now set up a joint management committee to run operations at Kaesong, which last week set a restart date for the complex.
The committee has also reached agreement on smoother access to the site for South Koreans by expanding permitted border crossing times and is negotiating about improving communications there.
The Koreas have also agreed to open the site to foreign investors - a move seen as making it harder for North Korea to unilaterally close the complex again.
South Korean firms will be exempt from taxes for the rest of the year, to offset losses incurred while the complex was closed.
But some local businessmen remain worried about the risks of doing business with Pyongyang.
Q&A: Kaesong Industrial Complex
"Honestly, I still feel a bit nervous, because you never know whether the North will change its mind in the future," a textile company manager told the French news agency AFP. "Who knows if a crisis like this won't happen again?" he said.
The shutdown was the first for the Kaesong complex since it was opened more than a decade ago.
It came during a period of very high tension on the Korean peninsula.
The 12 February nuclear test led to expanded UN sanctions which, along with an annual US-South Korean joint military drill, angered Pyongyang.
It threatened attacks on multiple targets in the region, prompting warnings - and displays of high-tech military hardware - from the US.
Tensions have eased somewhat in recent weeks, however.
The two Koreas have also recently agreed to hold the first reunion of families separated by the division of the peninsula after the 1950-53 Korean War later this month. It will be the first such reunion in 10 years.

Output: South Korean workers have returned to the Kaesong industrial park in North Korea, five months after work was halted amid high political tension.


Input: Consider Input: The 25-year-old was volunteering for a children's charity in Uganda when staff received news that a woman had died - leaving behind seven children.
The youngest was a baby boy who didn't even have a name.
With no-one to take care of him, he was given over to staff at the charity.
Emilie, from Leigh Sinton, Worcestershire, became the baby's sole carer and had sleepless nights looking after the boy, who became known as Adam.
Now, she is fundraising to help cover the costs of formally adopting the youngster and bringing him back to live in the UK.
She has received more than £15,000 in donations, with the majority being raised since her story was shared online on Sunday.
She says the response has been "amazing" and it takes her on the next step to finally becoming Adam's mum.
Emilie told BBC News: "I've raised far more than I ever thought I would.
"I thought I'd be pestering family and friends, so it's insane but amazing at the same time.
"I'm so grateful. I've been getting messages from people in China, Australia and Germany.
"People have been telling me how inspiring I am and how it's lovely to read something nice.
"But this is just my life."
Emilie's journey started in September 2014 when the charity she was volunteering for in Uganda received a call about a newborn boy in need.
They arrived at the burial of a woman who had died because of excessive bleeding after birth. Her children included baby Adam.
"He had not received any breast milk or formula and there was no one able to care for him. His mum left this world before even giving him a name," said Emilie.
"We took him in and I became the little one's sole carer. The sleepless nights were down to me, but they were no bother. I felt privileged to do it.
"I didn't do much but never a day went by where I was bored. I could sit and watch him for hours."
Over the next two years, Emily visited Adam as often as she could while working in a teaching job in the UK.
But the short visits were not enough and she moved back to Uganda in August 2016 after finding work at an international school.
Now Adam, who is two-and-a-half, lives with her full time while she tries to adopt him.
Emilie said: "I feel like his mum already. We had such a strong bond every time I was coming out but especially now since he's been living with me.
"He calls me mum."
Emilie has to foster Adam until August before she can apply to the Ugandan courts to legally become his parent.
She will then need to get permission from the UK to bring the little boy back to Britain.
She is hopeful that they will be living together in the UK by the end of the year.
Emilie said she had planned to fund the adoption herself until she lost her job in December, prompting her to set up a Go Fund Me crowdfunding page to pay for the process.
Her parents help support her living costs and she has taken another teaching position to cover Adam's school fees.
Emilie admits becoming a mum at the age of 25 had not been on her agenda, but she doesn't regret the path she has taken.
"It was not in my plan, but for the last two-and-a-half years Uganda is all I've thought about. I'm either talking about it or thinking about it.
"I imagined I wouldn't have kids for another 10 years but I don't regret it.
"It will be amazing to bring Adam home."
While Emilie has received overwhelming support for her decision, some online comments have questioned why she wants to remove Adam from his home country.
"I've been coming back to Uganda for him and I want to continue to do that," she said.
"I've done my best to keep him in touch with the village he came from so he can see his neighbours.
"I do my best. But a mother's love is one of the most important things and he's never going to have that here."

Output: When Emilie Larter held a five-day-old orphan in her arms, it set her on a journey to becoming a mum.


Input: Consider Input: Jake Berry told the BBC the government is committed to improving transport links in northern England.
When asked by a BBC reporter whether HS3 will happen, he replied "yes."
It comes as former Chancellor George Osborne wrote in the Financial Times urging Theresa May to commit to the scheme.
Mr Berry said: "What we've seen... is a government who's recognised the problem, launched the Northern Powerhouse project just three years ago and is determined to improve transport across the north, actually so we can see our economy grow..."
But he did not disclose details including timescales for the project.
Mr Berry made the comments while on a visit to Hull to see the city's regeneration work.
In Tuesday's Financial Times, Mr Osborne said: "Northern Powerhouse Rail, or HS3, must be included in the next stage of the government's high-speed network."
He said it would help the prime minister to "relaunch her premiership" and that a "full-blown attempt to rebalance the economy of Britain" was needed.
More than 70,000 people have signed a petition calling for Transport Secretary Chris Grayling to back the rail improvements, also called Northern Powerhouse Rail, and to give transport authorities in northern England the same powers as they have in London.
Meanwhile, 50 business and civic leaders from across the north of England are set to hand a letter to the government later demanding an increase in transport spending.
Drax Power chief executive Andy Koss, Greater Manchester Chamber of Commerce chief executive Clive Memmott and York College principal Alison Birkinshaw are among the signatories.
In the letter, published in the Yorkshire Post, they wrote: "Connecting our great cities of the north with a world-class, higher-capacity rail network is not only fundamental to the success of the Northern Powerhouse, it is fundamental to the success of the entire country.
"We are calling on you to back this success and back NPR."
Last month, the government scrapped the planned electrification of railway lines in Wales, the Midlands and the north of England, prompting anger from local authorities and businesses.
Days later, Mr Grayling backed proposals for Crossrail 2 - a north-east to south-west railway in London - sparking further fury from political leaders outside the capital.


Output: High-speed rail lines across the north of England, from Liverpool to Hull, "will happen", the Northern Powerhouse Minister has said.
