"Persons included in the list will be personally informed by the Ministry of Foreign Affairs about the entry ban," the ministry said, adding that it would not itself publish the names on the list.
However, there is nothing preventing those named from going public themselves, which is what MP Rihards Kols (National Alliance) did. Kols was the main sponsor of the bill as it passed through Saeima.
Saņēmu ziņu no @Arlietas, ka Krievija mani iekļāvusi savā melnajā sarakstā. Ņemot vērā, ka biju Magņitska sankciju iniciators, šāds lēmums nepārsteidz, taču vienlaikus vēlreiz apstiprina, ka strādājam pareizajā virzienā! #MagnitskyAct #sanctions pic.twitter.com/1FhAVAo5L7— Rihards Kols (@RihardsKols) June 19, 2018
Also on the list is Unity party parliamentary leader Hosam Abu Meri.
Tikko saņēmu ziņu, ka Krievija mani ir iekļāvusi “melnajā sarakstā” par atbalstu Saeimas lēmumam noteikt sankcijas Sergeja Magņitska lietā iesaistītajiem. Tā ir ideja, par ko stingri iestājos es un #JaunāVienotība. Magņitska likuma pieņemšana bija tiesiskas valsts goda lieta!— Dr. Hosams Abu Meri (@H_AbuMeri) June 19, 2018
But it wasn't just politicians on the Russian list with journalist Pauls Raudseps also saying he had been informed of his inclusion.
Tikko uzzināju, ka esmu iekļauts Krievijas "melnajā sarakstā". Arī Maskavā lasa @irlv :D— Pauls Raudseps (@raudseps) June 19, 2018
The submission of such a list is a response by the Russian Foreign Ministry to the decision of the Saeima of 8 February this year to introduce a "Magnitsky Law" in Latvia which imposes sanctions on persons suspected of involvement in the death in custody of lawyer Sergei Magnitsky, who was attempting to expose a huge fraud.
"The Latvian Foreign Ministry is not surprised at the submission of such a list, and believes that such a step is not aimed at improving bilateral relations," the ministry noted.
Latvia's "Magnitsky list", which is similar to those in force in several other countries, is understood to contain 49 persons linked to the Magnitsky scandal. This year, on February 22, Foreign Minister Edgars Rinkēvičs made a decision to declare persons named on the list as person non grata in Latvia.
