According to the Chinese Embassy in Paris, there have been no reports of casualties of Chinese nationals so far.
About seven well-coordinated shootings and bombings rocked central Paris Friday night, one of which turned into a hostage taking at the Bataclan theater and concert hall where hundreds of people were attending a rock concert.
At least two explosions were heard near the national stadium Stade de France where a France-Germanyfriendly soccer match was being played, attended by French President Francois Hollande.
Investigators said at least eight attackers were dead, with seven of them having blown themselves up.
Hollande, who has canceled his trip to Turkey for the upcoming G20 summit, will chair a defense meeting Saturday morning after the deadly attacks have shaken the country's security policy ahead of a high-profile international climate conference scheduled for the end of this month.
Hollande declared late Friday night a state of emergency across France, saying "unprecedented terrorist attacks are ongoing in Paris."
The French presidential office clarified early Saturday that the country has restored border controls but has not closed borders.
The French Foreign Ministry said airports and train stations will be open, and services will be assured.
The Chinese embassy in Paris issued a security alert late Friday, asking Chinese nationals in France to stay indoors and pay close attention to police information and local media reports about the incidents.
The embassy also urged the Chinese to follow police instructions in case of a security or identity check.
Belgium said Saturday it has boosted checks on its borders, especially on its border with France, following the Paris attacks.
The country also urged increased vigilance for big events over the weekend but said it was not necessary to increase the alert level.
Meanwhile, several U.S. cities including New York, Boston, Chicago and Los Angeles bolstered security on Friday night, but law enforcement officials said the increased police presence was precautionary rather than a response to any specific threats.
The New York Police Department (NYPD) said officers from its Counterterrorism Response Command and other special units were deployed in areas frequented by tourists, and at the French Consulate in Manhattan.
"Teams have been dispatched to crowded areas around the city out of an abundance of caution to provide police presence and public reassurance as we follow the developing situation overseas," the NYPD said in a statement.
The Port Authority of New York and New Jersey said police were on heightened alert at all of the agency's bridges, tunnels and rail facilities, as well as at the World Trade Center in lower Manhattan. It said it was increasing patrols and checking of bags, buses and trains.
Los Angeles Police Department said it had enhanced forces at critical infrastructure sites and will add more officers to patrol at large public gatherings.
Canadian Prime Minister Justin Trudeau said Friday night that he has spoken to members of his national security team to ensure the safety of Canadians in the wake of the Paris attacks.
"We will keep people apprised as more unfolds but I have been speaking with our national security team to ensure that everything is being done to keep people safe," he said.
Singapore on Saturday raised its security alert level and stepped up security measures, border checks and vigilance.
"Together, everyone plays a part to keep Singapore safe and secure. We encourage everyone to remain vigilant and report any suspicious activities or persons to the authorities," Home Affairs Minister K. Shanmugam said in a statement.
