The Chinese ambassador to Cuba, Hua Xin, described Washington's accusations regarding alleged Chinese intelligence facilities on the island as "unfounded," and accused the U.S. government of fabricating justifications for a possible military intervention.
"A lie repeated a thousand times remains a lie", the diplomat wrote on X on Monday.
The ambassador added that the accusations from Washington "serve to seek pretexts for their own subversive attempts and military intervention against Cuba."
"The relations between China and Cuba are transparent and cannot be defamed or slandered. We urge the U.S. to stop repeatedly making unfounded accusations and blaming others to divert attention from its own responsibilities," the publication warns.
"China will continue to firmly support Cuba in defending its national sovereignty and opposing foreign interference," the text concludes.
Hua Xin's reaction came hours after Secretary of State Marco Rubio presented a 100-page report from the State Department titled "Cuba: The Capital of 21st Century Communism," which documents nearly seven decades of Cuban espionage and dedicates a specific chapter to the presence of Chinese and Russian intelligence on the island.
According to that document, Cuba hosts 18 known signal intelligence facilities, three of which are actively operated by China and two by Russia, and the intelligence personnel from both countries on the island has tripled since 2023.
The Wall Street Journal also reported that China and Cuba signed a secret agreement to build a new facility capable of intercepting communications in the southeastern United States, in exchange for several billion dollars.
The stance of Beijing was reinforced this Tuesday by the spokesman for the Chinese Ministry of Foreign Affairs, Lin Jian, who described the relationship between China and Cuba as "legitimate and transparent" and dismissed the accusations as "rumors and defamations."
"Inventing excuses and spreading rumors to defame cannot serve as justification for the brutal blockade and illegal sanctions of the United States against Cuba," said Lin Jian.
The Cuban regime also responded.
Cuban Foreign Minister Bruno Rodríguez accused Rubio on Monday of creating a "fraudulent pretext" to justify military aggression, while President Miguel Díaz-Canel called Rubio "corrupt" and linked him to drug traffickers in a post published this Tuesday on X.
The diplomatic escalation is part of the Trump administration's maximum pressure policy towards Havana: since January 2025, Cuba has been back on the list of state sponsors of terrorism and has received over 240 sanctions.
In January 2026, President Trump declared a national emergency citing Cuba as a threat to national security, while the U.S. ambassador to the UN, Mike Waltz, warned on July 12 that Washington "will no longer tolerate" the presence of Chinese and Russian intelligence facilities on the island.
Hua Xin has been the most active Chinese diplomatic voice in defense of the Cuban regime for months.
On July 9, he published a supportive video following a UN vote on the embargo, in which he expressed that China trusts that Cuba will achieve "development and prosperity".
Rubio's report concludes with a warning that encapsulates Washington's stance: "Confusing Cuba's poverty with its harmlessness completely misjudges the threat. Its power has always been ideological, subversive, and parasitic."
