This article opens with:
Vladimir Putin was due to visit Pakistan this week, but has postponed his trip indefinitely and given no reason for his decision. Sadhavi Chauhan believes, however, that this setback is no threat to increased Russian cooperation with Pakistan and other Central and South Asian countries.
It ends with:
The postponement of Putin’s visit is undoubtedly a symbolic blow to Pakistan's efforts to diversify its strategic allies and do away with its image of bandwagoning with America.... However, it needs to be stressed that Putin has postponed his trip and not cancelled it. ...... There is a definite rapprochement between the two, even though their current bilateral engagement continues to be limited.

In a curious twist of timing the Pakistani Army go to Moscow:
...the Russian capital is set to welcome General Ashfaq Parvez Kayani on 3rd October. It is worth noting that his trip continues to be on course despite the cancellation of Putin’s visit.
