Syria has sent military trainers to Saudi Arabia, where they are helping prepare Saudi and Yemeni loyalists for the war against the Houthis.
Moreover, according to the AP news agency, Damascus is preparing to send about 600 more special forces soldiers to Saudi Arabia, who may be deployed on the border with Yemen.
It is worth noting that Al-Shara'a's adviser earlier denied even reports that the Saudis asked Damascus to send its army to participate in the war, and later the Syrian government also stated that it did not intend to send troops to the area.
As we can see, the new Syrian government are good politicians: they know how to say A, but do B, which is the basis of all political activity.
