Hua responded thus to new reports circulated yesterday about the evacuation of two USA officials working in the consulate of the southern city of Guangzhou due to mysterious health symptoms, registered before in another government official.
The administration of U.S. President Donald Trump, which has partly rolled back a detente with Cuba, first charged diplomats were the victims of "sonic attacks" and Cuba as the host country was at a minimum responsible for their safety. It added that Havana had taken note of the most recent case, reported by the U.S. embassy on May 29, about an employee who was said to have fallen ill as a result of "undefined sounds" at his place of residence.
Nauert also said that remaining USA government personnel and their families in Guangzhou would also be able to request testing if they "noted concerning symptoms or wanted baseline screening".
Global Affairs Canada is working to determine if any Canadian diplomats in southern China have been affected by a mysterious ailment that has already sickened a number of American diplomats and bears similarities to the unexplained illness suffered by Canadian and USA government workers in Cuba.
US personnel in Havana began reporting the incidents in 2016, and they were first disclosed publicly a year ago.

Canada in April also ordered families of diplomatic staff in Cuba to return home after mysterious health symptoms were detected in 10 Canadians stationed on the island.
"It appears that we have identified a new syndrome that may have important public health implications", senior author Douglas H. Smith, director of Penn's Center for Brain Injury and fix, said at the time.
At least one employee has suffered a mild brain injury, and several others have returned to the U.S.to undergo medical evaluations.
Secretary of State Mike Pompeo announced on Tuesday the formation of a task force in response to "unexplained health incidents" affecting USA diplomats and their family members. There are about 170 USA diplomats or employees and their families in Guangzhou. In a statement to CBS News, Lenzi said the ordeal has been "stressful" for his family. The consulate opened months after the establishment of diplomatic relations between Beijing and Washington in 1979 and moved to its new purpose-built facility in 2013. It is also the only USA diplomatic installation in China authorized to process immigrant visas and handle adoptions.

The possibility remains that Cleveland could retool and make another run, but doing so would require some serious creativity. Mitchell and James' games could clash a bit - neither are pure shooters - but it's a situation worth exploring.
