This week's inauguration of a new Red Sea Egyptian military base was pregnant with the symbolism of the rivalries shaping the future of the Middle East as well as north and east Africa.

The inauguration took on added significance as rebel Libyan Field Marshall Khalifa Haftar, backed by United Arab Emirates crown prince Mohammed bin Zayed and Egyptian general-turned-president Abdul Fattah al-Sisi, snubbed Russian president Vladimir Putin by refusing to agree to a ceasefire in the Libyan war.

Haftar's refusal thwarted, at least temporarily, an effort by Russian president Vladimir Putin and Turkish president Recep Tayyip Erdogan to structure the ceasefire so that it would align opposing Russian and Turkish interests, allow the two parties to cooperate in the exploitation of Libya's energy resources, and protect a Turkish-Libyan maritime agreement creating an Exclusive Economic Zone that strengthens Russian-backed Turkish manoeuvres in the eastern Mediterranean.

The manoeuvres are designed to thwart a Greek-Cypriot-Israeli agreement to build a pipeline that would supply gas to Europe, reducing European dependence on Russian gas in the process.

Critics charge that the maritime agreement that would limit Greek-Cypriot Israeli access to hydrocarbons in the Eastern Mediterranean, violates the Law of the Sea.

Warning that it would block European Union backing for any Libyan peace deal as long as the Turkish-Libyan maritime agreement was in place, Greece was one of the countries Haftar visited in the days between his rejection of a ceasefire and a conference from Libya hosted by Germany that is being held in Berlin on January 19.

Haftar's rejection came as Turkish troops arrived in Libya to bolster forces of the internationally recognised government of prime minister Fayez al-Sarraj, defending the capital Tripoli against an eight-month-old assault by the field marshal's rebel Libyan National Army (LNA) that is backed by Russian mercenaries with close ties to the Kremlin, the UAE, Saudi Arabia and Egypt.

Prince Mohammed's presence at the inauguration of the Egyptian naval base underlined the UAE's influence in Egypt since it backed Al-Sisi's 2013 military coup that toppled the country's first and only democratic elected president and the Emirates' determination to counter Islamist forces as well as Turkish influence in Libya and the Horn of Africa.

UAE and Egyptian backing of Haftar is not just about countering jihadist and non-jihadist Islamists as well as Turkey, but also Qatar, Turkey's ally, which also supports the Libyan rebels.

The UAE-Turkish-Qatari proxy war in Libya is increasingly also coloured by Prince Mohammed and Al-Sisi's opposition to efforts to resolve divisions among the Gulf states that spilled into the open with the declaration of a Saudi-UAE-led diplomatic and economic boycott of Qatar in 2017.

Saudi Arabia has hinted in recent months that it may be amenable to an easing of the boycott, a move that is believed to be opposed by the UAE as long as Qatar does not make significant concessions on issues like freewheeling broadcaster Al Jazeera and support for political Islam.

The new naval base's location symbolises Egypt's conundrum that also poses a problem for the UAE at a time that Egypt is at odds with Ethiopia over the operation of a giant dam that Ethiopia is building on the Blue Nile.

Stepping up involvement in Libya risks Egypt becoming embroiled in two conflicts at the same time.

Egypt claims the dam puts a million Egyptian jobs, US$1.8 billion in economic output annually and electricity valued at US$300 million at risk.

The base is aimed at "securing the country's southern coasts, protecting economic investments and natural resources and facing security threats in the Red Sea," according to a spokesman for Al-Sisi.

The president has warned that Egypt would take all necessary measures to protect its rights to the Nile waters.

So far, Egypt is banking on mediation to help it avoid being trapped between a rock and a hard place by achieving a ceasefire in Libya that would keep Egypt's hands free to deal with Ethiopia were a conflict to erupt.

The question is whether Haftar, who without signing the ceasefire agreement reportedly told German officials that he would adhere to its terms, and the UAE are willing to play ball.

The proof will be in the pudding. German Chancellor Angela Merkel raised the stakes by insisting in advance of the Berlin talks that they ensure "that the weapons embargo is adhered to again."

The United Nations has accused the UAE together with several other countries, including Turkey, of violating the UN embargo.

As a result, it may be the UAE rather than Haftar who has a decisive voice in Berlin.

Said North Africa expert Ben Fishman: "Until Abu Dhabi pulls back its drones, operators, and other crucial military support, the prospects for Libya's stability will remain dim. Besides the fact that they provide the greatest advantage to Haftar's forces, focusing on the Emiratis also makes sense because the other foreign players currently have reasons to de-escalate on their own."
