 A government-funded research team from Seoul National University found the footage, which was filmed in 1944 by an American soldier, in the United States National Archives after a two-year hunt. 
 
 “South Korea has not had its own data on comfort women and (has) been relying on Japanese and American data,” said Kang Sung-hyun, an academic on the team. 
 
 “It is crucial for South Korea to have our own data for the issue of comfort women,” he said. 
 
 The 18-second black-and-white clip shows seven women lined up outside a brick house, being questioned by Chinese soldiers. The women were found by U.S.-China allied forces in China’s Yunnan province, the research team said in a statement. 
 
 The women were registered by U.S. soldiers, the research team said. Two of the women in the video had already appeared in previously released photos of “comfort women”. 
 
 The term is used to describe girls and women from South Korea, China, the Philippines and elsewhere, who were forced into prostitution in Japanese wartime military brothels. 
 
 South Korean activists estimate that there may have been as many as 200,000 Korean victims. 
 
 Japan and South Korea agreed to resolve the issue “finally and irreversibly” in 2015 if all conditions were met. Japan made an apology and promised one billion yen ($8.84 million) for a fund to help victims. 
 
 However, the issue continues to strain relations between the two countries. 
 
 Japan wants South Korea to remove a statue near the Japanese consulate in Busan city commemorating Korean comfort women, as well as another near the Japanese embassy in Seoul, saying that the presence of the statues violates the 2015 agreement. 
 
 South Korean President Moon Jae-in suggested during his campaign for a May 9 election that most South Koreans did not accept the 2015 deal negotiated by his conservative predecessor Park Geun-hye and Japanese PM Shinzo Abe, and that he could try to renegotiate it. 
 
 Since the election, he has not directly addressed whether he will seek to renegotiate the pact. The issue is likely to be discussed when he meets Abe on Friday on the sidelines of the Group of 20 summit in Hamburg, Germany. ||||| Media playback is unsupported on your device Media caption First known footage of 'comfort women' 
 
 South Korea has released what it says is the first known footage of "comfort women" forced to work as sex slaves for Japanese soldiers during World War Two. 
 
 Filmed by US troops in China, the clip was found by government-funded researchers at Seoul National University in US archives. 
 
 The 18-second clip shows several women lined up talking to a Chinese soldier. 
 
 South Korean activists estimate 200,000 women were forced into brothels for Japan's military. 
 
 They are believed to have been mainly from Korea, but also from China, Indonesia, the Philippines, and Taiwan. 
 
 Some of the women were willing, others were lured with the offer of paid work as cooks or cleaners and many were forced, a UN report said. 
 
 Until now, the only records of women forced into sexual slavery by the Japanese military during World War Two had been photographs and survivor testimonials.

 The research team says the footage was filmed by joint US-Chinese troops in China's Yunnan province which was previously occupied by Japan. 
 
 The seven Korean women were freed in 1944 and the officer speaking with them has been identified as a Chinese captain of the China-US Combined Force, the team said. 
 
 The issue has long strained the relationship between South Korea and Japan over a perceived lack of adequate apology and compensation from Japan. 
 
 In 2015, the two countries reached a settlement whereby Tokyo formally apologised and agreed to pay 1bn yen ($8.3m, £5.6m) to fund victims. 
 
 Many Koreans though viewed the apology as insufficient and the issue continues to plague ties. 
 
 In January, Japan temporarily withdrew its ambassador to South Korea over a "comfort women" statue placed outside the Japanese consulate in Busan. 
 
 A similar statue has also been placed outside Japan's consulate in Seoul, and Tokyo wants both these statues to be removed. 
 
 Correction 31 July 2017: This article has been amended to make it clear that not all the "comfort women" were coerced.
– It's just 18 seconds long, but a new video released by South Korean researchers makes history for the worst of reasons. The clip shows Korean "comfort women" held as sex slaves by the Japanese military, reports the BBC. It's believed to be the first such film clip known to exist, though images of "comfort women" had previously surfaced in still photographs. The good news is that the video shows the women after US and Chinese troops arrived to free them in China's Yunnan province in 1944. A research team from Seoul National University found the footage in the US National Archives after a two-year search, reports Reuters. An American soldier is believed to have filmed the scene, in which a Chinese officer talks to the women lined up in front of a building used as a brothel. Japan forced an estimated 200,000 women to work as sex slaves for its soldiers during World War II. (Earlier this year, South Korea angered Japan with a statue honoring the women.)
