Prince Harry is set to embark on a packed solo trip to New York City next month – at the same time that his brother, Prince William, will likely host a summit in Manhattan.

The Duke of Sussex, 39, will ‘be in town to advance a number of his patronages and philanthropic initiatives,’ a spokesperson confirmed to DailyMail.com.

The trip is set to take place during UN General Assembly High-level Week and Climate Week, the latter of which runs from September 22 until September 29.

His older brother Prince William, 42, may also be in the city at that time for the third annual Earthshot Prize Innovation Summit, which will be held at The Plaza Hotel on September 24.

It’s unknown if the Prince of Wales will attend for sure, but he was present last year at the same event.

The Duke of Sussex, 39, will ‘be in town to advance a number of his patronages and philanthropic initiatives,’ a spokesperson told DailyMail.com

During Harry’s trip, he will ‘participate in engagements with African Parks, The HALO Trust, The Diana Award, and Travalyst,’ a spokesperson for Prince Harry said.

‘In addition, he will be furthering the work of The Archewell Foundation, the nonprofit organization he co-founded with his wife Meghan Markle, The Duchess of Sussex.’

If Prince William does come to New York when Harry is there, it’s likely the brothers will steer clear from one another, as a source told The Sunday Times earlier this month that the siblings hadn’t spoken in ‘two years.’

It was said that the last time they talked was at their grandmother Queen Elizabeth’s funeral in September 2022.

The insider described the ‘estrangement’ as ‘dreadfully sad,’ adding that Prince William doesn’t even want Harry at his coronation when the time comes.

‘This year his focus has very much been on his wife, his children and his father. His brother isn’t really something that’s discussed,’ they said.

Prince William’s wife Kate Middleton, 42, revealed that she was battling cancer earlier this year.

Harry and Meghan allegedly learnt of the Princess of Wales’ diagnosis at the same time as the general public – when she announced it to the world in a heart-wrenching video message filmed in the gardens at Windsor.

Despite living more than 5,000 miles away in their $14.65 million Montecito mansion, a source close to Harry and Megan said they reached out privately to the Waleses to wish them well – but the contact was not reciprocated.

In Harry’s 2023 memoir Spare, the Prince made a series of explosive accusations about his brother.

He claimed that William and Kate were the ones who encouraged him to wear his infamous Nazi costume to a party in 2005, and that his brother  once physically attacked him during a 2019 altercation regarding his wife, Meghan.

He said his older brother called the former actress ‘difficult,’ ‘rude,’ and ‘abrasive,’ before things turned physical.

‘He grabbed me by the collar, ripping my necklace, and he knocked me to the floor,’ he wrote.

‘I landed on the dog’s bowl, which cracked under my back, the pieces cutting into me.’

In 2021 – months after he and Meghan announced that they were permanently stepping down as royals and moving to California full-time – Harry told Oprah that he and William were ‘on different paths.’

‘I love William to bits, he’s my brother, we’ve been through hell together… but we’re on different paths,’ he said.

‘The relationship is space at the moment. Time heals all things – hopefully.’

Prince William was also set to appear at the first Earthshot Prize Innovation Summit back in September 2022, but canceled following the death of grandmother, Queen Elizabeth.
