China and Cuba have reached a secret agreement for China to establish an electronic eavesdropping facility on the island, in a brash new geopolitical challenge by Beijing to the U.S., according to U.S. officials familiar with highly classified intelligence

Officials familiar with the matter said that China has agreed to pay cash-strapped Cuba several billion dollars to allow it to build the eavesdropping station and that the two countries had reached an agreement in principle. 

“Joe Biden needs to wake up to the real Chinese threats on our doorstep,” Nikki Haley, a former South Carolina governor and United Nations ambassador and current Republican presidential candidate, wrote on Twitter.
