BRUSSELS, Jan 15 (Reuters) - The European Commission

will fully enforce its rules governing social media and other

large online platforms and has not delayed any cases against

U.S. Big Tech, the EU digital chief said on Wednesday.

"There haven't been any delays," Commission Vice President

Henna Virkkunen told reporters, referring to the Digital Markets

Act (DMA), which imposes antitrust obligations and the Digital

Services Act (DSA), which covers content moderation.

Virkkunen said she had seen reports that the EU was delaying

investigations, such as into Apple ( AAPL ), Meta and

Google, but said the probes were still in a technical

phase, which includes exchanges with companies, before decisions

could be taken.

"We are fully enforcing the DMA and the DSA," she said.

Virkkunen said the two acts were very powerful tools

applying to all companies, including European companies,

operating services in the European Union to ensure a fair and

safe online environment for all.

She also said the DSA was protecting, rather than limiting,

freedom of speech.

Meta chief Mark Zuckerberg said last week, while

announcing Meta had scrapped U.S. fact-checking programs, that

Europe had an ever increasing number of laws "institutionalising

censorship".

Zuckerberg also called on U.S. President-elect Donald

Trump, who starts his second term on Monday, to stop the EU from

fining U.S. tech firms.
