Popular short-video app TikTok, owned by China's ByteDance, has said it plans to open its first European data centre in Ireland with an investment of about €420 million.

In a blog post, Roland Cloutier, Global Chief Information Security Officer of TikTok, said the data centre will create hundreds of new jobs, enable faster loading time and safely store European user data.

"This data centre signals our long-term commitment to Ireland and we expect the data centre to open and be operational by early 2022," Mr Cloutier said.

TikTok is in talks with Microsoft about selling its US operations, while coming under fire from President Donald Trump over national security risks.

Mr Trump said he will ban the service in the United States on 15 September if there is no sale.

ByteDance said on Monday it was considering moving TikTok's headquarters overseas, following a British media report that the unit could relocate to London.
