Chinese President Xi Jinping delivered a message for the world during his opening speech at the 19th Communist Party Congress: China supports an open economy, and it will further liberalize its markets to foreign investors.
But while the leadership talks of financial liberalization, some facets of life inside the world's second-largest economy are becoming a lot less free.
That's especially true for digital communication inside China. Regulators have moved aggressively to curtail what the country's more than 750 million internet users can or cannot do online. While Beijing has shut out access to Google and Facebook in the past, new restrictions introduced this year have been some of the strictest ever, according to experts.
This year, authorities have cracked down on China's top video-streaming websites, doubled down on their crackdown of virtual private networks (VPNs), removed foreign TV shows from online platforms, required users to register to online forums with their real names and introduced laws that hold chat group admins accountable for what is said in their spaces.
New rules also require online news websites to be overseen by government-approved editorial staff and for workers to have reporting credentials from the central government.
Those limitations are likely here to stay, and may even grow, tech experts and china watchers told CNBC.
Internet users in China have long relied on circumvention tools to access hundreds of websites that have been blocked by the country's censorship apparatus.
Zahra, a student who has been living in the mainland for six years, had relied on VPNs to get past China's infamous "Great Firewall" and connect to the outside world. It also allows users privacy by hiding browsing activities from internet service providers.
The 23-year-old medical student, who asked to be identified by only her first name, told CNBC that VPNs allowed her to access YouTube and numerous reference websites that were relevant to her coursework.
While Beijing allowed users some wiggle room in the past, commentators said pressure had been mounting on authorities to rein in China's growing online space. Unlike the heavily regulated offline media in the country, the internet had allowed anyone to disseminate information and express critical opinions with little chance of punishment.
"The increasing pressure to gain control over online media is longstanding, reflecting Xi's goal to treat online media in the same way as traditional media," Paul Triolo, practice head for geo-technology at consultancy Eurasia Group, told CNBC.
As a result, authorities this year have aggressively targeted VPNs as part of what they characterized as an effort to clean up China's domestic internet.
Though quite a few VPN services are still functioning on the mainland, a source told CNBC in July that some of the remaining companies could end up collaborating with the authorities and hand over user data when requested.
Zahra told CNBC that it has become harder in recent months to rely on VPNs to access banned websites from the mainland. Many of the services, she said, were either not working or the connections through them were very slow.
"It's like being shut off from the world," she said.
It's not just VPNs, either. Authorities have also stepped up restrictions in other areas to control the online narrative surrounding the country's national and political identity.
The moves from the Chinese government keep "surprising me (in not a good way) in terms of what else they can regulate, control and censor," Lokman Tsui, an assistant professor at the Chinese University of Hong Kong, told CNBC in an email. "Let's also not forget that they push propaganda and misinformation actively."
He even predicted that Beijing officials could begin "taking a more active role outside their borders. There have been signs of that: lobbying at the UN level, the kidnapping of the booksellers, the great cannon, etc. "
Reports have previously detailed the "Great Cannon" — a term coined by the University of Toronto's Citizen Lab for a Chinese tool that can flood a website with traffic to overwhelm its servers and, as a result, force it offline.
For now, Tsui explained the current restrictions to control the domestic internet are on multiple levels that "push the Great Firewall even higher."
On a technical level, he said, China is increasing disruptions to messaging services like WhatsApp or circumvention tools like VPN. Existing regulation such as real-name registration are being enforced more strictly and new laws are holding more platform stakeholders liable for online content, he said.
"Controls on new media are much stricter now than we have seen at any point since the dawn of the internet," David Bandurski, co-director of the China Media Project and a fellow at the Robert Bosch Academy in Berlin, told CNBC.
Since regulators have "effectively neutralized" the dissemination of any unwanted information in traditional media, "the real heart of controls is shifting to cyberspace," he added.
Beijing has often made headlines for restricting the flow of information online, but this time is fundamentally different, experts said.
Historically, authorities have tightened controls over the domestic internet in the lead up to the once-every-five-years Communist Party Congress. Even though the event drew to a close on Tuesday, regulators are unlikely to now roll back many of the tighter regulations, analysts said.
There are two kinds of restrictions used by the authorities.
First are the publicly announced moves introduced by regulatory bodies, explained Rogier Creemers, a researcher at Leiden University in the Netherlands. So-called special measures are the other kind of restriction. They are aimed at creating a stable online environment during a major event like the Party Congress, Creemers explained.
Companies themselves may seek to clamp down on their users ahead of such important national occasions, said Charlie Smith, the co-founder of China censorship monitor GreatFire.org, who operates under a pseudonym. Such private sector measures include preventing certain videos from being shown or not letting users alter their profile pictures.
"These are moves being made to make sure that your users do not do anything stupid during the Congress," Smith said. "These restrictions will be lifted as soon as the meeting is over."
But Smith said the crackdown on circumvention tools like VPNs were likely to stay and the "current state of difficulty" that the Chinese encounter when trying to access the free internet is going to be the "new normal."
Creemers concurred, telling CNBC that broader regulations were "likely here to stay."
Eurasia Group's Triolo added that Xi's vision of cyber-sovereignty means that "China should be able to control and monitor all internet traffic that traverses China's internet infrastructure."
On top of all the external controls, Beijing is also considering taking a stake in some of China's largest internet companies, according to the Wall Street Journal. Planting a flag in those firms would likely give the Chinese government a more absolute role in corporate decision-making.

Jun. 1 - China's new cybersecurity law goes into effect, which requires foreign businesses in the country to store crucial data on local servers. The move draws criticism due to vaguely defined terminology and worries over potential surveillance.
Jun. 22 - Beijing shuts down online video services of three Chinese media sites: Weibo, ACFUN and iFeng.com. Previously, authorities shuttered 60 popular celebrity gossip social media accounts for not being in line with "core socialist values," according to Reuters.
Jun. 29 - The Ministry of Culture shuts down 12 live-streaming mobile apps and hands out administrative punishments to another 20.

Sept. 7 - China issues new rules that require internet chat service providers to verify the identities of users and keep a log of group chats for no less than six months, according to Reuters. Those rules also require those who manage chat groups to monitor the online activity of their fellow forum members. The regulations also said that chat group service providers had to establish a credit scoring system.
Oct. 1 - New rules require internet users to register their real names when using online forums. Authorities have attempted to push "real-name" registration before — users of social media platform Weibo and online portal Sohu have been asked register their identities in the past — but those initiatives were not as strictly implemented.
