I have not heard of his interviews or other public statements entirely devoted to political issues, but his opinions can be seen from statements that occasionally slip out in his speeches on other topics. It seems that he believes, or at least wants the reader to think that he believes, that the Western world is hostile to Russia, and that it inspires and encourages the Russian opposition. He also approves of the official Russian policy towards Ukraine. However, he shies away from answering questions whether the current policy of Putin and Russian government is in the interests of people.
Below are some of Lukyanenko's statements (in shortened translation)
Our opposition does not advocate its own interests, but serves as a
tool for achieving other counties's goals. ... This opposition offers
us to return to 1990s and lay under the authority of the USA.
No one doubted Putin’s victory, but the activity of people has proved
to be higher than expected. The reason lies in the pressure that the
West is now putting on our country. In fact, an undeclared war is
being waged against us.
Among Ukrainian authors there are people who accepted euromaidan with
an open mind. Frankly, I have nothing to talk with them about.
These people supported euromaidan wholeheartedly. I see no sense and I
have no need to communicate with them.
