Bouthaina Shaaban made the remarks in a statement to journalists after meeting visiting China’s Special Envoy for Syria Xie Xiaoyan and the accompanying delegation in Damascus on Saturday.
While the US and its allies sponsor Daesh, the alliance supported by Russia and China stands against terrorist expansion in the Arab country, Shaaban said.
Russian and China, two of the five veto-wielding permanent members of the United Nations Security Council, have vetoed resolutions against the Syrian government that is battling foreign-sponsored terrorists since 2011.
There are UNSC resolutions, under which those responsible for committing, organizing and supporting terror acts as well as facilitating the movement of terrorists must be held accountable, but these motions have not been implemented at all, the Syrian official noted.
UNSC Resolution 2253, adopted unanimously in December 2015, covers asset freeze, travel ban, arms embargo and listing criteria for Daesh, al-Qaeda militants and “associated individuals, groups, undertaking and entities.”
Elsewhere in her remarks, Shaaban said that the Syrian army and its allies had recently managed to reach the Syria-Iraq border and “dealt a severe blow to the terrorists" through unified efforts, underlining the importance of strengthening communication between the two neighbors in that regard.
Washington’s agenda intersects with that of Daesh, which serves the interests of Israel, she added.
The Syrian official also denounced as unjustified the US deployment of rocket launchers to southern Syria and its attacks on the army positions.
Earlier this week, Russia said the US had deployed the M142 High Mobility Artillery Rocket System (HIMARS) launchers from Jordan to its base in the Syrian town of At-Tanf, warning that the equipment could be used against Syrian government forces.
Additionally, in two occasions in June and May, US warplanes attacked a Syrian military position near At-Tanf, killing an unspecified number of people and causing some material damage.
The US claimed that the Syrian forces who came under the attack posed a threat to its forces in Syria.
The Syrian army denounced the assaults, saying they demonstrated US support for terrorism, at a time when the Syrian army and its allies were making gains against Daesh militants.
