I wish we could read the diplomatic cables, but we can't, and all we have is a conservative opinion columnist's characterization of the cables. The columnist, Josh Rogin, has refused to publish the cables.
But I strongly suspect that Rogin is mischaracterizing the cables. He claims that they express alarm over a lack of trained staff at the Wuhan Institute of Virology. Staff from the WIV are trained at a US national lab in Galveston. I think it's highly likely that the directors of the WIV told US diplomats that that support was important, and asked for it to be increased. US diplomats then wrote that the lab needed more trained staff, and that the US should increase support. Someone in the Trump administration then found this cable and "leaked" it to a friendly commentator, Rogin. Rogin then characterized it as pointing out severe problems in the lab, without letting anyone see what the cable actually says.
I'd bet the reason Rogin won't publish the cable is that on the whole, it probably doesn't support the characterization he's trying to make.
