The Chinese ambassador to Cuba, Hua Xin, described the accusations from Washington regarding alleged Chinese intelligence facilities on the island as "unfounded," and accused the U.S. government of fabricating justifications for a future military intervention.
“A lie repeated a thousand times remains a lie”, wrote the diplomat on X on Monday.
The ambassador added that the accusations from Washington "serve to find excuses for its 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 firmly continue to support Cuba in the defense of its national sovereignty and in its opposition to foreign interference," concludes the text.
Hua Xin's response came hours after Secretary of State Marco Rubio presented a 100-page report from the Department of State titled "Cuba: The Capital of 21st Century Communism," which documents nearly seven decades of Cuban espionage and devotes 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 have 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 position of Beijing was reinforced this Tuesday by the spokesperson of the Chinese Ministry of Foreign Affairs, Lin Jian, who characterized 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 justify the brutal blockade and illegal sanctions imposed by the United States against Cuba," stated Lin Jian.
The Cuban regime also responded.
The chancellor Bruno Rodríguez accused Rubio on Monday of building a "fraudulent pretext" to justify military aggression, while President Miguel Díaz-Canel called Rubio "corrupt" and linked him to drug traffickers in a thread posted this Tuesday on X.
The diplomatic escalation is part of the maximum pressure policy of the Trump administration towards Havana: since January 2025, Cuba has once again been listed as a state sponsor of terrorism and has received over 240 sanctions.
In January 2026, President Trump declared a national emergency, identifying 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 defending the Cuban regime for months.
On July 9, he released 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 is to completely misunderstand the threat. Its power has always been ideological, subversive, and parasitic."
