BRUSSELS, (Reuters) – European Union lawmakers and countries of the European Union reached a tentative agreement on Friday to create new rules that will require tech companies to be more vigilant in policing content and pay a fee for monitoring compliance.

It took 16 hours to reach an agreement. Margrethe Vestager, EU Antitrust Chief, has created the Digital Services Act (DSA), which is part of her strategy to limit the power of Alphabet (NASDAQ) unit Google and Meta as well as other U.S. technology giants.

Vestager stated in a tweet that “We have a deal regarding the DSA. The Digital Services Act will ensure what is illegal offline, is also seen online and treated as such – not just as a slogan or as a fact.”

The DSA allows companies to be fined up to 6% for any violation of the rules. Repeated breaches can result in them being banned from doing business within the EU.

Last month, lawmakers and the 27-country bloc backed Vestager’s historic rules known as the Digital Markets Act. This law could make it harder for Google, Amazon, Apple (NASDAQ) and Meta to alter their European core business practices.
