SEOUL/DANDONG, China (Reuters) - A Canadian man under investigation in China for threatening national security said he ran a prayer and training facility outside the Chinese city of Dandong that was frequented by North Koreans, many of whom became Christians before returning to the isolated country.
Kevin Garratt, who with his wife Julia Dawn Garratt is being investigated for suspected theft of military and intelligence information, also ran a coffee shop in Dandong, which was closed on Tuesday with a notice in the window reading: "See you soon."
"When God says to go and do something - yeah we have a choice - but when God's presence says go, we really better go," Garratt said in an audio file posted on the website of Terra Nova Church based in British Columbia, Canada.
"All these people could've stayed in China, where it's easier, where they could eat three meals a day," he added, addressing a congregation at the South Korean-Canadian church in Canada last November.
"But they chose to go back - everyone of them. And 99 percent of the people we meet go back to North Korea, because they have to preach the gospel in North Korea - they have to. Because God's compelled them to go."
Terra Nova Church and its pastor did not reply to several emails and calls for comment on the audio file, which is dated Nov. 3, 2013.
One of their sons, 27-year-old Simeon Garratt, told Reuters he knew nothing about the sermon. The son, based in Vancouver, said his father had been in the city last November. The website has since removed all the audio sermons.
Garratt's claims, which could not be independently verified by Reuters, were likely to cause consternation in North Korea, a secretive country where religion is banned and proselytising is severely punished.
Peter's Coffee House, run by the Garratts on the border with North Korea, advertises tours to North Korea on its website.
Kevin Garratt leads the tours and knows North Korean tour guides, some of whom frequent the shop on rare visits to China, said a source familiar with the trips. The source declined to be identified because of North Korea's sensitivity to religious groups.
The case bears similarities to that of U.S. missionary Kenneth Bae, who was sentenced by Pyongyang last year to 15 years hard labour for attempting to overthrow the state.
Bae operated businesses in Dandong and he used his tour company, Nation Tours, to take foreign missionaries across the border into North Korea.
China's Foreign Ministry said on Tuesday that the Garratts were under investigation. Their whereabouts are unknown.
Simeon Garratt said his parents were "openly Christian" and they sent goods such as food to impoverished North Korea.
Neither the Chinese Foreign Ministry nor the official Xinhua news agency, which first announced the investigation, mentioned religious activities.
Doing anything that could be seen as overtly religious along the sensitive border with North Korea was risky, experts said.
"North Korean authorities cooperate really closely with China basically throughout the border region ... of course there is more risk along the border," said Adam Cathcart, a specialist on China-North Korea ties at the University of Leeds.
The Garratts did little to hide their Christianity, according to people who had been to their Dandong cafe, which they said was known as a meeting point for foreign Christians in the area.
"It couldn't be any more Christian. It's always busy and they play Christian rock music in there," said Gareth Johnson of Young Pioneer Tours, a travel company based in China that takes tourists to North Korea and who has visited the shop.
The cafe was closed on Tuesday when a Reuters reporter went there. A notice on a chalkboard in the window said "see you soon." Nearby, a laminated sign posted on the cafe's wall said "Let your faith be bigger than your fear."
While China can be suspicious of Christian groups, underground churches and foreign missionaries usually operate without too much harassment, experts said.
"North Korea, as you know, is very oppressive, it's very challenging, they desperately need hope and we get this very special privilege of working with some of these incredible people in North Korea," Garratt said in his address last year.
Sources with knowledge of fund-raising for similar projects at overseas churches warned that some statements by missionaries in the field may be exaggerated.
"They have to give the impression that they're making change on the ground and doing God's work," said one source working in the region who requested anonymity.
"They have to show the money they raised is worthwhile. I'm not sure if they do as much as they say they're doing."
While Dandong is close to a porous North Korean border crossed by hundreds of refugees escaping their homeland every year, none of the sources said there was any indication the Garratts worked with North Koreans seeking to flee.
Western missionaries working along the border tend to use China as a foothold from which to focus missionary work on North Korea itself, either by setting up businesses or by running tour groups designed to take Christians into the isolated country.
South Korean missionaries also operate in the area, but are not permitted to enter North Korea except in rare circumstances, and usually work more to aid refugees.
China regards North Korean defectors as economic migrants rather than refugees and forcibly repatriates those found on Chinese soil.
Border officials, who are susceptible to bribes, sometimes turn a blind eye to potential defectors or to traders moving Chinese goods to sell on the North Korean black market.
The Garratts were from Vancouver and opened their cafe in 2008.
Sources described the small coffee shop as a buzzy, contemporary place with large tables and a fast Internet that held regular live music and English-language events. There are no references to Christianity on its website.
Free English lessons are also offered at the cafe, which sells hamburgers, cheesecake and milkshakes.
Peter's Coffee House is one of several western cafes or restaurants run by Christians along China's border with North Korea. Some offer free English lessons, and are staffed by locals or visiting Christians.
Sources working in the area said the owners of other Christian-run cafes there might also have come under scrutiny from authorities, although Reuters was unable to confirm those accounts.
"I know they were Christian, but I don't know what kind of work they were involved in," said David Etter, a U.S. citizen who knows the Garratts.
His own Christian-run coffee shop and restaurant, Gina's Place in the northeastern border city of Yanji, was forced to close recently, citing a lack of customers.
"The struggles have made us stronger, have increased our faith," Etter's wife Regina wrote of the closure in a blog post last month.
