TikTok's Chinese owner, ByteDance, has signed binding agreements with US and global investors to operate its business in America, TikTok's boss told employees on Thursday.

Axar.az reports that half of the joint venture will be owned by a group of investors, including Oracle, Silver Lake and the Emirati investment firm MGX, according to a memo sent by chief executive Shou Zi Chew.

The deal, which is set to close on 22 January, would end years of efforts by Washington to force ByteDance to sell its US operations over national security concerns.

It is in ​line with a deal unveiled in September, when US President Donald Trump delayed the enforcement of a law that would ban the app unless it was sold.

In the memo, TikTok said the deal will enable "over 170 million Americans to continue discovering a world of endless possibilities as part of a vital global community.

Under the agreement, ByteDance will retain 19.9% of the business, while Oracle, Silver Lake, and Abu Dhabi-based MGX will hold 15% each.

Another 30.1% will be held by affiliates of existing ByteDance investors, according to the memo.

The White House previously said that Oracle, which was co-founded by Trump supporter Larry Ellison, would license TikTok's recommendation algorithm as part of the deal.

The deal comes after a series of delays.
