Since Super Junior's debut in South Korea, the group endeavored to share an equal share of influence across Asia. The group has paid many visits to countries outside of their homeland, especially China and Thailand. Although Super Junior has yet to make an Asian concert tour, there has been speculation where Super Junior will target the overseas markets and hold their own major concerts in 2008.^[23]

[edit] Expansion to Thailand

Super Junior made their first overseas performance in Thailand on March 9, 2006 at a music ceremony.^[24] In effect of the appearance, the group's new single with TVXQ moved up to #8 on Thailand's Channel [V] Music Chart.^[24] Soon afterwards, "Miracle" debuted as #1 in the charts on March 21, 2006. "Miracle" was the first song produced by SM Entertainment that topped overseas music charts in Thailand of Channel V. The song stayed as #1 for four consecutive weeks.^[25] Siwon was also chosen to be the endorser of 12 Plus, and filmed several comercials in Thailand. During Super Junior's performance at the Academy Fantasia in Thailand on July 14, 2007, several hundred Thai fans were crowded around the stage to watch the group perform. Some fans even fainted due to excessive heat and limited space while many others were injured due to the heavy amount of shoving and pushing.

The group's third single for SMTown, released in the 2007 SUMMER SMTOWN - FRAGILE album on July 5, 2007, debuted as #18 on Thailand's International Channel [V] Music Chart on the week of July 29, 2007. The single jumped to #8 the week after, and on the third week the single advanced to #1.^[26] The single was a remake of H.O.T.'s "Full of Happiness" (행복). Aside the International Channel [V] Music Chart, which was #1 for six consecutive weeks, the single also made it to #1 on the POP Channel International Chart and the MTV International Chart in Thailand. The single has been staying strong as the #1 position on these three charts.^[8][9]

[edit] Expansion to the Chinese market

In early April 2006, Super Junior's only Chinese member, Han Geng, visited China for the first time since his debut to promote Super Junior. Since then, Han Geng and the rest of Super Junior gave continuous visits to China. On June 12, 2006, along with performances of Kangta & Vanness, Super Junior made their debut performance as a group in China performing "U" and "Miracle". After the performance in Qingdao, Super Junior became the most frequently reported Korean artist from the Chinese media.^[27] The group has since made over ten visits to the country since April 2006. After filming the Chinese film A Battle of Wits in 2006, Siwon made frequent visits to China to promote the film. Along with the rest of the cast of the film, Siwon toured four cities in China, the stops including Beijing, Shanghai, and Hong Kong. During one of Han Geng's visits to China in July 17, 2007, close to 300 fans welcomed him at the airport.^[28] On July 18, 2007, the rest of Super Junior arrived in Shanghai to attend a 2007 Cyworld event. Due to previous chaos and confusion caused by the amount of Chinese fans at the airport, and also because of a tight schedule, the organizers for Super Junior decided to lead the group to exit the airport through the VIP section instead of meeting the fans through the main entrance.^[29]

On August 8, 2007, Han Geng and Siwon visited China again and traveled to Changsha to participate in a variety show that was suppose to be held earlier on April but was postponed because of the April 19th accident. Over 700 fans were at the airport to welcome the two.^[30]

Due to continuous visits to China, sources say that the group has serious intentions to target the Chinese market, with a Chinese version of "U" released in the Chinese editions of the single, U, on June 15, 2007. It is also said that the group will record as well as perform more Chinese singles in the future, and will also release a Chinese album.^[31] Super Junior announced that they will hopefully hold their own concert in China by 2008.^[32] On October 2, 2007, the group's management released an official statement introducing that a new Super Junior subgroup is in plans to debut in China next year in 2008.^[33]
