The Seventh Summit of the Americas  will make history with Cuba's participation for the first time in 50 years, after the suspension of the island from the Organization of American States (OAS) in 1962. In Panama, US President Barack Obama and Cuban President Raul Castro will meet for the first time since the reestablishment of diplomatic relations  between the two countries.

This year, 35 heads of state will attend the meeting on April 10 and 11 under the motto “Prosperity with Equity: The Challenge of Cooperation in the Americas.” However, the new US-Cuba relations and the crisis in Venezuela  are expected to steal the spotlight as well as be a source of conflict. As GV contributor Elaine Díaz  pointed out in an article on Medium, Cumbre de las Américas: El impacto de las relaciones Cuba-Estados Unidos en las dinámicas hemisféricas  (Summit of the Americas: The Impact of the US-Cuba relations in the hemispheric dynamics):
El contexto económico y político de América Latina, los cambios en los escenarios institucionales de las organizaciones intrarregionales y el deshielo de las relaciones entre Cuba y Estados Unidos constituyen factores imprescindibles para comprender el desarrollo de la Cumbre de las Américas a celebrarse en los próximos días en Panamá.
The economic and political context of Latin America, institutional changes within intraregional organizations and the thaw in Cuban-US relations are essential factors to understanding the development of the Summit of the Americas, which will take place in the coming days in Panama.
So, what can we expect from the summit?
While there, a group of Latin American ex-presidents will denounce what they see as a “democratic disturbance” in Venezuela, in order to find an “alternative” to the Venezuelan crisis.
Last month, the American government suspended visas and froze the US accounts seven senior Venezuelan government officials accused of human rights violations during the protests of February 2014. These protests, which challenged Venezuelan President Nicolas Maduro, left 40 people killed and opposition leaders in jail.
However, the sanctions had a different effect. Declarations saying that Venezuela was “a menace” to the security of the United States generated concern in the region regarding possible interference in internal issues. The Venezuelan government took the opportunity to launch a campaign in order to collect 10 million signatures asking US President Obama to repeal the sanctions. People joined the campaign on social media under the hashtags #ObamaDerogaElDecretoYa  (“Obama, repeal the decree now”) and # VamosXLos10millones  (Let's get those 10 million):
Working non-stop for food security. Let's get those 10 million, which ratify our will to be free

In the middle of all these tensions, Obama will meet with Maduro while in Panama.
The issue of alleged human rights violations in Venezuela and the letter that more than 20 presidents wrote denouncing the status of democracy in the country will only be discussed in private meetings at the summit. Moreover, these meetings will only take place if Panamanian President Juan Carlos Varela  proposes it and the proposal is approved by the rest of the leaders.
While Venezuela will surely capture a lot of attention during the summit, many netizens think like Twitter user La Divina Diva :
De hecho en una cumbre americana no deberia hablarse de ningun pais en particular sino de los problemas generales de la region #MiOpinion

In fact, during a Summit of the Americas they shouldn't talk about a country in particular, but about the general problems of the region #MyOpinion
Panama will also be visited by business people at the II CEO Summit of the Americas , held at the same time as the summit in which participants will discuss commercial opportunities and investment possibilities that could be beneficial to Latin America's social and economic growth.

As pointed out by Rodrigo Pardo,  the head editor of Semana magazine, there will be ex-presidents, journalists, political prisoner's wives and CEOs in Panama, but the situation regarding human rights, political prisoners, limitations on freedom of speech and the growing authoritarianism in Venezuela (or in Nicaragua, or in Bolivia, o in Ecuador) will not be key agenda points during the official summit.
