He said the Russian government's determination to continue joint work to combat terror has not been undermined, and the two countries will continue to move on the same path until stability and security are fully restored to Syria.
Syrian and Russian bombardment battered the province of Quneitra, which remains mostly in rebel hands, for a second day on Monday.
Britain-based Syrian Observatory for Human Rights said an overnight "frenzied" bombing campaign continued into Wednesday, with at least 350 missiles lobbed into Nawa and its surrounding areas.
A Syrian army source quoted by state media said the army had made territorial gains in Quneitra province where it seized the town of Mashara, about 11 km (7 miles) from the Golan frontier.

It even brokered a deal this week to evacuate thousands of besieged people from a pair of pro-regime towns in northwest Syria. Under the recent surrender deal rebels would hand over weapons, and fighters who do not wish to live under state rule would be transferred out. The evacuees' first stop is the government-controlled city of Aleppo.

Syrian President Bashar Assad said Sunday the success in driving the opposition out of Daraa embodies the will of his army and allied forces to "liberate all of Syrian territories" of "terrorism".
Quneitra is a thin, crescent-shaped province that lies along the buffer zone with the Israel-occupied Golan to the west.
If that is true, it is not clear why Iranian Supreme Leader Ayatollah Ali Khamenei's top adviser visited Moscow "on a strategic mission", in his words, and met with Putin while Israeli Prime Minister Benjamin Netanyahu was on a similar tour to Moscow nearly at the same time.
Multiple parties including Egypt also told Hamas that the kites must be stopped "to prevent giving Israel an excuse to launch a major military offensive". This was probably an allusion to the fact that Iran has been using its presence in Syria as a leverage to exert pressure on Israel, the United States' most important ally in the region. The Observatory said at least 12 were killed as rescuers struggled to get to the casualties.
As such, his remarks seemingly provide at least partial confirmation of a flood of rumors from the Israeli and U.S. press that Israel, Saudi Arabia and the United Arab Emirates have offered a deal to Putin, and that the United States itself expressed interest in it.
Israel has refused to comment.
