International and K-pop stars alike will join forces to help children around the world suffering due to the COVID-19 pandemic through a charity concert. MBC works with World Vision to bring the "World is One 2021" online concert to reach every fan worldwide.

MBC has now reaveled the lineup of performing artists that will take the stage to perform and give awareness to the kids' suffering because of the pandemic. Once again, the world of K-pop will cross boundaries to show unity in times of crisis.

The performers include NCT 127, Stray Kids, Kim Chung Ha, ITZY, MAMAMOO's Solar, Wei, STAYC, ONF, LOONA, ONEUS, CIX, SECRET NUMBER, OMEGA X and Just B, per All Kpop. International stars like Sonnet Son, Forti Di Quattro, New Hope Club, Christopher, Siedah Garrett, Now United and Sting will also join the event.

With stars this big, each one of the acts is said to have its own set of special stage. There will also be films, collaborations and more. One of the must-sees is the duet between the original songwriter of Michael Jackson's big hit "Man in the Mirror," Siedah Garrett, and Solar to give the 1980s classic a new life.

Meanwhile, the event's K-pop performers can also go head-to-head with their international counterparts with their equally successful careers in the music scene. NCT 127 recently became a double-million seller, thanks to their new album, "Sticker," KpopStarz noted.

CIX also almost tripled their first-week sales on the Hanteo Chart with their first-ever full album, "OK' Prologue: Be OK," which now sold more than 110,000 copies. In addition, though Secret Number, OMEGA X and Just B were just recently introduced, they were already making big names in the K-pop world.

Elsewhere, aside from the performances, "World is One 2021" will also feature the clip that will show the kids in Kenya and Zambia, Africa. It will reveal the dramatic changes in their lives that happened with the help of the projects the World Vision is developing. '

MBC and the Humanitarian aid organization will also present a singing choir's video for the first time. So, to tease fans of what they are about to see, the event organizers drop the official music video for the concert's campaign song before the event occurs.

LOONA Chu, WEi Kim Yohan and American Grammy-winning singer-songwriter Eric Bellinger can be seen here together. The "World is One 2021" online concert will stream live worldwide on YouTube on Oct. 30 at 8 p.m. KST.
