SHANGHAI/SEOUL, March 17 (Reuters) - Cai Yufang, 21, is a big fan of Korean television dramas like "Shopping King Louie", a show about a profligate chaebol heir who loses his memory and learns the value of love and labour from a sweet, simple country girl.

The Shanghai student is one of millions of young Chinese consumers with a huge appetite for South Korean pop culture whose regular viewing habits have been disrupted by growing political tensions between the countries.

The mainland chill on Korean content that follows Seoul's decision to deploy a missile defence system, however, is driving Chinese fans to get their "K-culture" fixes on peer-to-peer platforms instead of mainstream sites such as Youku, Tencent and iQiyi where some content has been taken down. The three sites did not respond to requests for comment.

"Korean dramas, and especially variety shows, are no longer being updated, so I can't watch any more. There are no links – it's a bit annoying, really," said Cai. "For a lot of young Chinese who like Korean culture, it's a real shame."

Cai added that eager viewers were already finding alternative channels. She has started following a group on a Chinese messaging service called "Watch drama together" that provides links to shows on file sharing platforms like Baidu Cloud.

The blackout reflects a wider cultural freeze, with South Korean singers and actors blocked, dozens of Korean-focused blogs suspended, tourism bans and product boycotts.

South Korea's soft power, especially its dramas and music, is a hot commodity.

Production values are generally smarter than those of other Asian markets and its snazzy fashion, hyper-stylized singers and well-choreographed dances have captivated audiences in the region since late 1990s.

China is South Korea's second-largest overseas market for dramas, songs and other media content. The fluid exchange of entertainment products has played a big role in strong, friendly ties between the two trade partners.

But for South Korea stars, recent tensions have hit music concerts to lucrative advertising gigs in China.

S.M. Entertainment, a music, talent and event promoter that houses popular Korean boy-bands EXO and SHINee, is among scores of firms that say their China businesses are affected following Seoul's decision to deploy a U.S. missile defence system within its borders to deter North Korea.
