US President Barack Obama is in Cuba right now--the first time a sitting US president has visited the country since 1928.

This is a big moment for Cuba and US-Cuba relations. For more than five decades, the US has pursued a largely isolationist policy towards Cuba, a former Cold War enemy.

Obama’s historic visit comes amidst recent efforts between the US and Cuba to normalize relations. Cuba is only 90 miles from the US state of Florida, but travel has been largely limited between the two nations until recently. In February 2016, the US restored commercial flights to Cuba for the first time in 50 years. Previously, only charter planes could fly between the two countries.

What’s on Obama’s schedule?

The US President will be in Cuba for three days to meet with Cuban President Raúl Castro, tour the city of Havana, and address the Cuban people.

Next month, I'll travel to Cuba to advance our progress and efforts that can improve the lives of the Cuban people.

After arriving in Havana, the Obamas were greeted by Cuban Foreign Minister Bruno Rodriguez. They first visited the newly reopened American embassy where Obama spoke of his trip.

"It's a historic opportunity to engage directly with the Cuban people," Obama told US Embassy staff.

The Obamas also got to take part in a walking tour of Old Havana

Obama greeted Cubans on the streets and spoke with locals.

Obama’s daughter Malia even got a chance to interpret Spanish for the president in a conversation with a Cuban restauranteur.

On Monday, Obama met with Cuban President Raúl Castro

The two leaders are holding meetings to discuss trade and economic liberalization to allow more US involvement in business on the island. A major topic will also be Cuba’s human rights record and allow democratic reform and basic freedoms for the Cuban people.

What are the impacts of his visit?

Obama’s visit will be a key step in allowing for the development of new economic opportunities for Cuba from increased openness and US investments. For example, the US Treasury already granted permission for Airbnb, Starwood Hotels, and Marriott International to offer accommodations in Cuba.  Obama will also announce a deal for Google to work with Cuban authorities to expand Cuba's wifi and broadband internet access.

His trip to Cuba has also brought attention to the Castro regime’s treatment of political dissidents. As a friendly gesture towards the US before Obama’s visit, Cuba released four dissidents whose anti-government protests resulted in imprisonment, but many more remain incarcerated. Just hours before Obama’s arrival, Cuban security agents detained dozens of members of the dissident group Ladies in White, who were holding a protest in Havana to demand the release of political prisoners.

What’s in store for the future?

On his last day in Cuba, Obama will deliver an address to the Cuban people and meet with dissidents and members of the opposition, including the Ladies in White.

Ending on a less controversial note, Obama will attend an exhibition baseball game between the Tampa Bay Rays and Cuba’s national team.

While much has been done much to thaw relations between the US and Cuba, some major obstacles remain, including concessions on human rights, economic freedoms and further opening of trade by the US.

Hopefully, renewed efforts by the White House to lessen the US economic embargo on Cuba, which has largely affected Cuba’s poor, will not just help open up opportunities for businesses and travelers but also allow the Cuban people to reap the benefits of economic progress.
