Selected excerpts :

I am bringing to this Assembly the voice of the “exploited and the humiliated,” as was said by Che Guevara in this same room almost 60 years ago.
We are a diverse group of nations sharing the same problems. We have just confirmed that in Havana, which was honored to host the Summit of leaders and other high representatives of the G-77 and China, the most representative, broad, and diverse representation that exists in the multilateral arena. [The G7 was created 9 years after the G77, who has expanded since, it deserves to be known, see this map]
During those two virtually tireless days, more than 100 representatives from the 134 nations making up the Group, raised their voices to call for changes that can no longer be postponed in the midst of the unjust, irrational and abusive international economic order that year after year, has deepened the enormous inequalities between a minority of well-developed nations and a majority that has not managed to get rid of the euphemism of “developing nations.”
We are united by the need to change, which has not been resolved, and the condition of being the principal victims of the current global multidimensional crisis; the abusive unequal exchange; the scientific and technical gap, and the degradation of the environment.
But we have also been united, for more than half a century now, by the inescapable challenge and the determination to transform the current international order, which is also exclusionary, irrational and unsustainable for the planet and non-viable for the well-being of all.
The countries represented in the G-77 and China, where more than 80% of the world population lives, not only have the responsibility of development, but also the responsibility to modify the structures that marginalize us from global progress and make many peoples of the South into laboratories of renewed forms of domination. A new and more just global contract is imperative.
At the current pace, none of the 17 Sustainable Development Goals[ for 2030] will be achieved, and more than half of the 169 agreed targets will not be met.
In the midst of the 21st century, it is offensive to the human condition that almost 800 million persons suffer from hunger in a planet that produces enough to feed all.
Equally outrageous is the fact that in the era of knowledge and accelerated development of information and communications technology, more than 760 million people — two thirds of them women — do not know how to read and write.
[Many more examples could be cited, it’s a problem of selfish(/nationalist/…) will not of means]
The efforts of developing countries are not enough to implement the 2030 Agenda. They must be supported by concrete actions to provide access to markets, financing under fair and preferential conditions, technology transfer and North-South cooperation.
We are not begging for alms or asking for favors.
The G77 demands rights and will continue to demand a profound transformation of the current international financial architecture, because it is deeply unjust, anachronistic and dysfunctional.
Because it was designed to profit with the reserves of the South; to perpetuate a system of domination that aggravates underdevelopment, and to replicate a pattern of modern colonialism.
We need and demand financial institutions within which our countries can have real decision-making capacity and access to financing.
A recapitalization of Multilateral Development Banks is imperative to radically improve their lending condition and meet the financial needs of the South.
The member countries of this Group were forced to allocate 379 billion dollars from their reserves to protect their currencies in 2022, almost twice as much as the amount of Special Drawing Rights that they were allocated by the International Monetary Fund (IMF).
A rationalization, review, and role change of credit qualifying agencies is needed. Equally imperative is to establish criteria that would go beyond the GDP to define the access of developing countries to financing under favorable conditions and adequate technical cooperation. While the richest countries fail to meet the commitment to allocate at least 0.7% of their NGP to Official Assistance for Development, the nations of the South need to spend up to 14% of their incomes to pay the interests associated with foreign debt.
Most of the G77 nations are forced to allocate more resources to servicing the debt than to health or education. What sustainable development can be achieved with that noose on their necks ?
The Group today reiterates its call on public, multilateral, and private creditors to refinance the debt with credit guarantees, lower interest rates, and longer expiration deadlines.
We insist on the implementation of a multilateral mechanism to renegotiate sovereign debt with an effective participation of the countries of the South
(…) The priority of the G77 is to change, once and for all, the paradigms of science, technology, and innovation, which is limited to the environment and perspectives of the North, thus depriving the international scientific community of considerable intellectual capital.
[At The G77+ Havana Summit,] we decided to resume the work of the Consortium of Science, Technology and Innovation for the South (COSTIS) with the purpose of promoting joint research projects and promoting the production chains that may reduce the dependence on the markets of the North.
We call on the richest nations and international bodies to participate in these initiatives.
Cuba will not cease in its efforts to promote the creative potential, influence and leadership of the G77. Our Group has a lot to contribute to multilateralism, stability, justice and the rational that the world requires today.

Added to the problems and challenges that characterize the reality of our nations and impact our peoples, are the unilateral coercive measures, euphemistically called sanctions, which have become a practice of powerful States that intend to act as universal judges to weaken and destroy economies and isolate and submit sovereign States.
Cuba is not the first sovereign State against which measures of that sort are applied, but is the one that has put up with them for the longest period of time, despite the world condemnation that every year is expressed almost unanimously in this Assembly, which is disrespected and unheard by the government of the biggest economic, financial and military power in the world.
We were not the first and have not been the last. Pressures to isolate and weaken economies and sovereign States are also affecting today Venezuela, Nicaragua and, both before and after, these have been the prelude of invasions and the overthrowing of uncomfortable governments in the Middle East.
We reject the unilateral and coercive measures imposed against Zimbabwe, Syria, Iran and the Democratic People’s Republic of Korea, among many others who suffer their negative impact.
We reiterate our solidarity with the Palestinian cause. We support the right to self-determination of the Sahrawi people.
Let us all struggle for a world of peace , without wars or conflicts.
And I can not stand in this world tribune without denouncing, once again, the fact that for 60 years now, Cuba suffers an asphyxiating economic blockade, conceived to depress its income and living standards; promote a continued scarcity of food, medicines and other basic inputs and damage its potential for development.
That is the nature and those are the objectives of the economic coercion and maximum pressure policy applied by the US government against Cuba in violation of International Law and the UN Charter.
Cuba has not implemented a single measure or action aimed at hurting the US, its economic sector, its trade, or social fabric.
Cuba has not engaged in any action threatening US independence, harming their sovereign rights, interfering in its internal affairs or affecting the well-being of its people. The US behavior is absolutely unilateral and unjustified.
The Cuban people are resisting and overcoming isolation day after day in the face of the merciless economic warfare which, since 2019, in the midst of the COVID pandemic, was opportunistically escalated to an extreme, cruel, and inhumane dimension. The impacts are brutal.
(…)
The US persecutes and has tried to prevent the supplies of fuel and lubricants to our country, an action that may seem unthinkable in times of peace.
In a globalized world, to prohibit access to technologies, including medical equipment with more than 10% of US components, is not only absurd but criminal.
