China's Secret Spy Base in Cuba Raises Concerns for US Diplomacy.

The United States has expressed concerns to Cuba about hosting Chinese spy operations on its territory, according to White House spokesperson John Kirby. Despite recent reports about a Chinese spy base in Cuba, Secretary of State Antony Blinken's planned visit to China later this week is expected to proceed. China denied using Cuba as a spying base, and Blinken stated that U.S. actions since President Joe Biden took office had slowed down China's efforts to expand its presence overseas.
