The extended blacklist will be published in the Official Journal of the European Union, which is a compendium of EU legislation. The sanctions will come into force the moment they appear on the website.
At an extraordinary meeting in Brussels on January 29, EU foreign chiefs said they were making a list of new names to be targeted for EU travel bans and asset freezes.
The meeting was called after a deadly shelling of the southern Ukrainian city Mariupol that killed around 30 people. Both warring sides in Ukraine blamed the other for the escalation in violence.
The ministers also agreed to prolong until September 2015 the existing curbs against 37 entities and 151 people, including Russian dignitaries and militias in the breakaway regions of Luhansk and Donetsk in eastern Ukraine. The individual sanctions were initially due to expire on March 15, 2015.
European Commission's spokeswoman Maja Kocijancic confirmed last Friday that the individual sanctions on 19 people and nine entities will come into force on February 16.
The new sanctions were delayed by a week pending crunch talks on Ukrainian reconciliation in Minsk, Belarus, where the leaders of Russia, Ukraine, France and Germany negotiated a 13-point plan outlining steps that are needed to be taken to bring peace to Ukraine. So far, the ceasefire that came into force Saturday night is holding, EU leaders said.
Last year, the European Union and its allies slapped Russia with several rounds of sanctions – including on energy, banking and defense sectors – over Moscow's alleged involvement in the Ukraine crisis, a claim that it has denied.
