ALGIERS: Algeria on Friday ruled out returning to roundtable talks over Western Sahara, days after the UN appointed a new envoy for the conflict. 鈥淲e confirm our formal and irreversible rejection of the so-called roundtable format,鈥� Algeria鈥檚 Western Sahara envoy Amar Belani told the APS news agency.

Algiers is seen as the main backer of the Polisario Front, which seeks independence in the disputed territory, mostly controlled by Algeria鈥檚 arch-rival Morocco.

The International Crisis Group wrote this month that 鈥淩abat considers Western Sahara a regional issue and the Polisario an Algerian proxy鈥�, meaning Morocco wants Algeria at the table in any talks.

But some Polisario officials demand a return to bilateral talks on what they see as 鈥渁 struggle by a colonized population for national liberation from a colonial power鈥�, the ICG report explained.

The last UN-led peace talks in 2019 involved top officials from Morocco, Algeria, Mauritania and the Polisario.

But they were frozen after UN envoy Horst Kohler quit the post in May 2019. He was finally replaced this month by veteran diplomat Staffan de Mistura. The Security Council is expected to renew the mandate of peace mission MINURSO by Oct. 27, and possibly call for new roundtable talks.

But Belani said Algeria had told the council it rejects the 鈥渄eeply unbalanced鈥� and 鈥渃ounterproductive鈥� format, warning it would thwart De Mistura鈥檚 efforts.

He accused Rabat of trying 鈥渢o evade the characterization of the Western Sahara issue as one of decolonization and to portray it as a regional, artificial conflict鈥�.

Tensions have mounted between Rabat and Algiers since Morocco last year normalized ties with Israel and won US recognition of its sovereignty over the Western Sahara, a former Spanish colony rich in phosphate and Atlantic fisheries.

Algeria, which has long supported the Palestinian cause as well as the Polisario, in August cut diplomatic ties with its rival over 鈥渉ostile actions,鈥� including alleged spying on its officials 鈥� accusations Morocco dismisses.

The standoff also came after the Polisario declared a three-decade cease-fire 鈥渘ull and void鈥� after a Moroccan incursion to break up a blockade of a highway into Mauritania.

Belani urged the UN to treat the issue seriously. 鈥淲e must recognize that the risks of escalation are serious,鈥� he said. 鈥淧eace and stability in the region are at stake.鈥�
