His remarks came as the Kurdistan Workers' Party (PKK) announced it was disbanding, an announcement that the Kurdish-led Syrian Democratic Forces (SDF) which control swathes of north and northeast said heralded a "new phase" for the region.

Shaibani told a news conference in Ankara with his Turkish and Jordanian counterparts that the PKK's move is "a pivotal moment" for regional stability.

Syria is "implementing the national accord with the Syrian Democratic Forces and incorporating all areas under central state control", he said.

In March, Syria's interim President Ahmed al-Sharaa and SDF chief Mazloum Abdi signed an agreement to integrate the civil and military institutions of the semi-autonomous Kurdish administration in the northeast into the national government.

The deal, agreed three months after the overthrow of longtime ruler Bashar al-Assad, is expected to be implemented by the end of the year.

"This process is complicated and sensitive but it is necessary," Shaibani said, adding that "delaying the implementation of this agreement will prolong the chaos, open the door to foreign interference, and fuel separatist tendencies".

"Our goal is not dominance but unification," he said.

"We are keen on implementing this agreement and we hope that the other side is seriously committed to implementing this agreement," he added.

- 'New phase' -

The Kurdish administration and its de facto army the SDF control most of the oil and gas fields in Syria.

The SDF maintains that it is independent from the PKK, but it is dominated by the Kurdish People's Protection Units (YPG), which Ankara views as a PKK offshoot.

SDF chief Abdi in a statement on X expressed appreciation for the PKK decision to disband, saying the step "will pave the way for a new phase for politics and peace in the region".

In February, Abdi said an initial call for the PKK to lay down weapons and disband did not concern his forces.

After years of marginalisation and repression under the Assad dynasty, the Kurds took advantage of Syrian government forces' withdrawal during the civil war, which erupted in 2011, to establish a semi-autonomous administration.

With US backing, the SDF played a key role in the fight against the Islamic State group, which was defeated in its last Syrian territorial stronghold in 2019.

Shaibani emphasised that "the unity of Syrian territory is non-negotiable, as Syria is an indivisible, unified state, sovereign over its land and will remain so".

"The rights of Kurdish citizens will be preserved and guaranteed on an equal footing with the rest of the Syrian people," he added.

Syria's Kurds have criticised a temporary constitutional declaration announced in March and said the new government failed to reflect the country's diversity.
