May be yes. May be no. But it looks suspicious enough to appoint a special prosecutor and investigate the allegations.
Though at this point, I'm not even sure "conspiracy" is the right word anymore. There is nothing "secret" with the situation.
(Also makes you wonder why analysts bother meeting with CEOs since the CEOs can't share non-public information.)
The US started the trade war and 'sanctions'. Just like the long-running low key trade war it started against the Eu in 2005. Its not China doing anything.
The US even violated or rejected many of the WTO rules it previously backed in enforcing on all other countries when it had the market advantage. Which is one reason why practically every single country outside various European ones are converging around China, India, BRICS etc - they see the US and its satellites as unreliable partners who would renege on any word anytime its convenient for them.
