Sarkissian served as the first chairman of the Global Council on Energy Security at the World Economic Forum, with which he has had a long association.

In an article in the Hollywood Reporter in March 2023, Sarkissian detailed the tense and dramatic events surrounding the creation of Wordtris and its sale to Spectrum Holobyte.

In April, he appeared on a podcast alongside Henk Rogers, the co-founder of Tetris, and Alexey Pajitnov, the creator of the game whom he had last seen in the Soviet Union.

In his short tenure, he initiated significant economic and political changes, including the abolition of the Ministry of Information, which paved the way for press freedom for the first time since Armenia's independence in 1992.

He also presided over a restructuring of Armenia's energy sector, which had suffered serious setbacks during the war with Azerbaijan, and oversaw reforms in the government and civil service.

On inauguration day, the government led by Karen Karapetyan resigned and parties in the National Assembly had a week to put forward their proposals for prime minister.

Armen Sarkissian is credited with playing a pivotal role in finding a peaceful solution, threatening to resign if there was any use of violence.

[4] An extensive profile of Sarkissian in the British magazine Spectator later observer that, "The Velvet Revolution was not preordained to be peaceful.

"While visiting the Kazakhstani city of Almaty in May 2019, he said that his country could become an "international financial center" and can become a "cooperation bridge between Eurasia and EU".

But due to the limits placed on his office by the Constitution, he was not allowed to play a role in the management of the war or the subsequent diplomatic negotiations.

[7] Sarkissian was a constant subject of often lurid conspiracy theories in some sections of the Armenian press, which routinely accused him of being a British spy, adducing as evidence for the allegations his friendships with British politicians and the then-Prince of Wales (now Charles III, who visited Armenia as a private guest of Sarkissian's in 2013.

[8] Sarkissian had long expressed frustration with the constraints on the presidency and the government's refusal to honour its pledge to reform the Constitution.

He had hinted to the British magazine The Spectator that he would resign if the Constitution remained unchanged, saying "I did not accept this job to feel honoured.

Sarkissian said Armenians were being forced to live: In a peculiar reality where the President cannot influence issues related to war and peace.

In a reality where the head of state and sometimes even his family become targets for attacks by various political groups… I thought it thoroughly and decided to resign as the President of the Republic of Armenia after almost four years of active work.

In the current challenging period for the state and the nation, the President does not have the necessary tools to influence the fundamental processes in domestic and foreign policy.

He explained that he had made a historic investment of $500,000 in a luxury hotel in St. Kitts and Nevis, which has conferred citizenship on foreign investors under a "citizenship-by-investment" programme since 1984.

Sarkissian had long been the target of frenzied speculation and allegations, including the claim that he had not disclosed his private wealth and that he was actively engaged as director in an overseas company while serving as President.

Following a lengthy investigation that lasted more than a year after Sarkissian's resignation, the Corruption Prevention Commission of Armenia found the allegations to be baseless.

Besides Armenian and Russian, two languages that Sarkissian grew up speaking, he was also fluent in English as a result of his time spent in the United Kingdom.

He was a personal friend of Charles III, who (as Prince of Wales) made a private visit to Armenia in 2013 as Sarkissian's guest.
