The Duke and Duke of Sussex may face a royal confrontation in New York City during their upcoming visit to the city.

It is possible that both Prince Harry and Prince William will be in New York City at the same time next month to attend to their work obligations.

The Duke of Sussex will attend the U.N. General Assembly High-level Week and Climate Week in New York City to promote his philanthropic initiatives.

"The rep added that he will participate in engagements with African Parks, The HALO Trust, The Diana Award, and Travalyst. Additionally, he will further the work of The Archewell Foundation, the nonprofit organization he co-founded with his wife Meghan, The Duchess of Sussex. Further details will be shared as we approach the week of events."

The event kicks off Sept. 22 and runs through Sept. 29.

The third annual Earthshot Prize Innovation Summit, co-hosted by Prince William's global environmental contest and Bloomberg Philanthropies, will take place at the Plaza Hotel on Sept 24. It is uncertain if William will attend this year's event.

Kensington Palace declined to comment on Planet Chronicle Digital's request.

The royal exit of Harry and Markle in 2020 has caused a persistent conflict between the brothers.

The reason for the couple's departure was due to the unbearable intrusions and racist attitudes of the British media, as they described it.

In February, after being diagnosed with cancer, Charles invited Harry to visit him in the U.K.

At the time, Hilary Fordwich, a royal commentator, told Planet Chronicle Digital that Harry was reportedly not permitted to stay at any royal homes and did not have a reunion with William.

This summer, Prince Harry steered clear of another confrontation with his estranged sibling.

In June, the Duke of Westminster and Olivia Henson got married at Chester Cathedral in northern England, and while the Duke of Sussex was invited, Harry declined to attend to avoid an "awkward" encounter with William.

According to Christopher Andersen, author of "The King," if Harry attended the wedding and sat in the back row, the media coverage and excitement surrounding the two brothers being in the same room would outshine the wedding itself, as reported by Planet Chronicle Digital.

"Harry's presence would have turned the affair into a media circus, and he didn't want to do that to his friend. If he learned that Harry had accepted the invitation, it's likely that William would have backed out. Harry knows this."

""William is not willing to give an inch, as evidenced by the lack of any indication that he is willing to compromise," he concluded."
