Rayhan, a popular singer whose music mixes Eastern melodies with Western pop, has given a concert on 14 February for years.
But this month the show has been cancelled, along with other events.
Instead of Valentine’s Day, the authorities are trying instead to promote the study and appreciation of a local hero, the Moghul emperor Babur, whose birthday falls on 14 February.
Babur, a descendant of Genghis Khan and founder of a culturally rich and tolerant empire across South and Central Asia, will be commemorated in readings and poetic festivals.
An official from the education ministry’s Department for Enlightenment and Promoting Values said it had issued an internal decree “not to celebrate holidays that are alien to our culture and instead promote Babur’s birthday”.
The official, who wanted to remain anonymous, said the decree had been in place for a while.
Local reports say the state information agency has in the past warned local publishers to avoid material on Valentine’s Day.
But a college student told the BBC that Valentine’s Day had become a new tradition celebrated among young people in particular, with souvenirs, cards and small presents exchanged between sweethearts.
It is not the first time that the authorities and the state media in particular have taken aim at what they see as damaging Western influences.
In the past few weeks there have been several articles attacking foreign soap operas from Mexico and Latin America for being too explicit and for undermining local values and traditions.
Similar criticism was levelled against hard rock and rap music in an extensive campaign a year ago. A Youth Channel on state TV labelled the music “Satanic”, feeding on drug addiction and immorality.
But observers say that the authorities’ approach to Western culture is largely inconsistent with state media attacking supposedly immoral content on TV and the internet, while not a word is said about the often raunchy music videos produced by the president’s daughter, Gulnara Karimova.
