It seems like girl group AOA is determined to take over the world stage.

On July 29, AOA released their third Japanese single "Heart Attack" and began holding promotional activities throughout the country. They already held an event in Nagoya on July 30, and they will hold events in Osaka on July 31 and Tokyo on August 1.

AOA will also release a Chinese version of "Heart Attack" in China and Taiwan on July 31. The group previously made a record of reigning over top 6 spots on Taiwan's Omusic K-pop download chart. The list was topped by Korean version of "Heart Attack," "Really Really," "One Thing," "Come to Me," "Luv Me," and "Chocolate."

In August, AOA will heat up the stages in the United States. The group will perform at the KCON music festival in LA and NY on August 2 and August 8 respectively. AOA's agency FNC revealed that with their KCON performance ahead, the group has been receiving many interview requests from various foreign media including Billboard.
