"The EU is ready to cooperate with the new government to help tackle the enormous challenges ahead", she writes.
On Saturday, parts of the transitional government were presented after the overthrow of former leader Bashar al-Assad. Among the ministers is Hind Kabawat, Minister for Labour Market and Social Affairs and the first woman in the new government.
Transitional President Ahmad al-Sharaa, who led the uprising against the al-Assad regime last autumn, has previously stated that elections could be held within four to five years.
The US is also welcoming the government.
We hope that this appointment (of government members) represents a positive step towards an inclusive and representative Syria, says American Foreign Ministry spokesperson Tammy Bruce.
