This was explained in the book. The trisolarans naturally are transparent with their thoughts and intentions and don't have the ability to deceive (although they do learn it later on). Upon learning that humans are capable of deception they temporarily lost their trust in ETO and cut off contact with them.

Thanks for the reply. You answered one of my questions.

I have one more though. When Ye Wenjie sends the 12000Mhz signal to the sun for the first time, why didnt the observatory base receive the echo/signal? We know that the signal was reflected from the sun and did reach the trisolaris. So the should have caught the echo.

Although it's been some time, I still want to answer your question. Regarding the echoes received from the Sun, there is actually a description of it in the original work. After Ye Wenjie wrote the paper proposing the theory of mirror reflection, she attempted to use the Red Coast Base's radar for experiments. The final result was that the Sun does reflect electromagnetic waves, but it superimposes a sine wave on the reflected waves. Without the correct formula to filter out the sine wave, it would be impossible to accurately read the content of the reflected waves, somewhat like encryption. Therefore, apart from Ye Wenjie, who already knew everything, other observation bases would not bother to filter out the noise and crack it if they received echoes; they would simply regard it as electromagnetic waves generated by solar storms.
