Home secretary Theresa May is said to have had positive discussions today with the social media firms over ways that they can help in efforts to tackle social disorder during times of unrest.
Earlier in the month, Prime Minister David Cameron said that the government was looking at whether it was "right and proper" for people to be prevented from using social networks such as Facebook and Twitter if they are suspected of plotting criminal activity.
The networks, particularly the semi-private BlackBerry Messenger (BBM) service, are thought to have been the conduit for much of the rallying this month in English cities.
However, the home secretary stressed to the social networks that today's meetings were "not to discuss restricting internet services", but rather to focus on how police can better use the websites to combat crime.
A Home Office spokesperson said: "The home secretary, along with the culture secretary and Foreign Office minister Jeremy Browne, has held a constructive meeting with ACPO [the Association of Chief Police Officers], the police and representatives from the social media industry.
"The discussions looked at how law enforcement and the networks can build on the existing relationships and co-operation to crack down on the networks being used for criminal behaviour. The government did not seek any additional powers to close down social media networks."
After the meeting, a spokeswoman for Twitter said that the microblogging site was "always interested in exploring how we can make Twitter even more helpful and relevant during times of critical need".
She added: "We've heard from many that Twitter is an effective way to distribute crucial updates and dispel rumours in times of crisis or emergency."
A Facebook spokesperson said: "We found today's discussion at the Home Office constructive and built on much of the work we are already doing with the UK authorities to ensure Facebook remains one of the safest places on the internet. We welcome the fact that this was a dialogue about working together to keep people safe rather than about imposing new restrictions on internet services.
"We were pleased to highlight our array of effective reporting tools and the relationships we have built with Law Enforcement to keep the site safe for the 30 million people in the UK who use Facebook - especially during times of crisis."
MPs and justice campaigners have expressed concern over the "harsh" response to the riots, after two men who used Facebook to incite violence were handed four-year prison terms.
A teenager was who posted a message on Facebook encouraging the rioters has also been banned by a judge from using any social networking websites for a year.
At the meeting today, Facebook stressed the "many positive purposes" it fulfilled during the riots, such as providing a platform to co-ordinate the post riots clean-up and bring communities together.
The firm said: "We were able to revisit the positive role Facebook played during the riots - from letting friends and family know they are safe to helping facilitate local clean-up operations. There is no place for illegal activity on Facebook and we take firm action against those who breach our rules."
