Just as President Abdo Rabbo Mansour Hadi and UN Special Envoy to Yemen, Jamal Benomar appeared as if they had eventually overcome the NDC (National Dialogue Conference) last hurdle, both the Southern Movement and the Houthis announced they withdrew from all negotiations.

The two factions have issued a statement this Tuesday in which they stipulated that unless a post-NDC roadmap is approved they will oppose any form of resolution. This new roadblock is bound to add to Yemenis’ frustration.

With Yemen unable to solve its political deadlock and move forward its transition of power, experts have warned the impoverished nation could lose its positive momentum and risk antagonize its population as democratic changes will remain unfulfilled, interrupted by politicians’ inability to reach a consensus.

More troubling yet, al-Harak, the Southern Secessionist Movement has called for a massive demonstration on Saturday to invoke its self-determination right and assert its claim for secession.

Six months of intense negotiations and a series of concessions have done little to tame the rebellious South and its dream to reform South Yemen.

Qassan al Shaabi, a high ranking leader of al-Harak told the Wall Street Journal on Monday that "90% of the southern people are against unity and still consider northerners as occupiers.” He then added, “We have always insisted for immediate separation from the north."

Unless officials manage to sell the concept of unity under a federal system to al-Harak and the Houthis, Yemen will remain in political and institutional limbo, something experts and the international community understand will be the undoing of the region as a whole.
