Pay attention to the wording:
Embarek said WHO team ruled out lab theory largely after questioning Wuhan Institute of Virology staff **about what they thought about the possibility**.
Let's repeat: 'about what THEY THOUGHT about the possibility'.
And Embarek doubled up and said in texto:
"They’re the best ones to **dismiss** the claims and provide answers to all the questions”
Let's repeat: "to DISMISS the claims".
Now there is nothing particularly special here.
Let's not forget that the #2 of the China's CDC is Dong Xiaoping, who was actually 'sanctioned' for his responsibility in the Beijing 2004 SARS leaks.
Best of all he was #2 on the Chinese side of the Feb 20 WHO joint mission.
But that's not the end yet, let's go back a little:
"They’re the best ones to dismiss the claims and **provide answers to all the questions**”
