BEIJING (AFP) - North Korea's premier pop group, the all-girl Moranbong band reportedly formed by leader Kim Jong-Un, has cancelled its first concert abroad, China's National Centre for the Performing Arts said Saturday.
The reclusive country's premier pop group was scheduled to perform at the venue in Beijing from Saturday evening as part of attempts to restore troubled ties between the traditional allies.
"We express deep regret for the inconvenience this may have brought you," the centre wrote on its official account website.
After the abrupt cancellation, the band's members headed to the capital's airport, according to Chinese news portal Sohu, which added that the performance hall had begun dismantling their stage.
Japanese network NTV showed footage of women in military coats arriving at the flight hub, while pictures of the band's disappearing act showed up on Chinese social media.
The photos show the women, clad in long coats and tall fur hats, getting out of a van in front of the airport, before striding past bystanders snapping pictures with their cell phones.
China has traditionally been North Korea's sole regional ally and main provider of trade and aid, but ties have become strained in recent years as Pyongyang has pressed ahead with internationally condemned nuclear tests.
Kim himself has yet to visit Beijing, three years after inheriting power from his father Kim Jong-Il.
There was no suggestion as to why the band's trip had been cut short.
On Chinese social media, Internet users suggested that the abrupt decision may have been related to Pyongyang's announcement this week that it had developed a hydrogen bomb.
"The next thing they'll do is test a nuclear weapon, and go against Xi Dada", one commentator said on Sina Weibo, a Twitter-like social media platform, using a common nickname for President Xi Jinping.
The band's arrival in Beijing was widely covered, but the show was not open to the public, the National Center for the Performing Arts in Beijing told AFP.
The band have shaken up the reclusive country's generally staid music scene with renditions of patriotic songs, along with Western hits such as "My Way" and the theme from Rocky performed on electric violins.
The concert in Beijing was billed as a "friendship performance" by North Korea's state-run KCNA agency, which praised the "worldwide stylish band" as "the first standard-bearer on the ideological and cultural front".
The Moranbong band first performed in 2012 and its members are reportedly hand-picked by Kim.
