古巴政权与美国敌对势力的合作

What happened: The Center for Strategic and International Studies (CSIS) confirmed, using satellite imagery, the completion of a circularly disposed antenna array in Cuba, suspected to be a Chinese spy base. Meanwhile, U.S. Senator Marco Rubio sanctioned the Cuban Institute of Friendship with the Peoples (ICAP), alleging its ties to U.S. left-wing NGOs and radical Marxists. Trump and Rubio have previously criticized Cuba for aiding U.S. adversaries.

Market impact: U.S.-Cuba relations remain tense, potentially impacting U.S. companies with operations in Cuba or those involved in U.S.-Cuba trade. Sanctions on ICAP could disrupt U.S. left-wing NGOs' operations, affecting their valuation and funding. Chinese involvement in Cuba may escalate U.S.-China tech tensions, impacting U.S. tech companies and defense contractors.

What to watch next: The U.S. State Department's response to the suspected Chinese spy base; updates on ICAP's operations and potential retaliation from Cuba or its allies; and U.S.-Cuba trade negotiations, with key dates including the U.S. midterm elections in November and potential changes in U.S. foreign policy.
