Day by day, JYJ's international activities as Korean representatives are attracting much attention. On August 26th,  'The 10th International Congress on AIDS in Asia and the Pacific' was held at Busan's BEXCO, and JYJ held a celebration concert for their appointment as goodwill ambassadors for UN's affiliated organization, UNAIDS, in the Asia-Pacific region. A group of 4,000 from more than 70 countries attended the event, and listened as JYJ delivered the message to strengthen efforts in AIDS prevention and awareness. Members Jaejoong and Yoochun stated, "AIDS is becoming a big issue internationally, and we are trying to do activities for its prevention and awareness." Junsu continued, "Even though AIDS is a fatal disease, you can live longer through steady treatment. However, since there is no perfect treatment, we need care and effort." Meanwhile, on September 4th, JYJ will appear as Hallyu stars and sing for the closing ceremony of the '2011 Daegu World Athletics Championships'. The '2011 Daegu World Athletics Championships' was organized by the International Association of Athletics Federation (IAFF), which drew over 2,000 of the world's athletes to the city of Daegu. JYJ will celebrate the successful conclusion of the 9-day competition with a charismatic performance that's sure to entrance worldwide fans. JYJ's agency, C-JeS Entertainment, stated, "JYJ's potential continues to grow as JYJ performs at worldwide concerts and showcases. Love calls for JYJ to attend these global events are never-ending."
