It comes down to trust them about what.

If I were engaged in anything hostile to Israel I utterly would not trust Israeli stuff. But Israel is normally quite careful about target selection, if I was not engaged in anything hostile to Israel I would expect anything they slip in to be secure and to not do any harm beyond it's existence. A scene from Lebanon not too long ago makes it very clear: A whole bunch of people milling about, setting up for selfies and the like--then we see the building behind destroyed by an airstrike. Clearly all those people around knew the building was going to be destroyed and they trusted Israeli accuracy enough to be standing not too far from where the bomb would land.

China, though, I would utterly not trust target selection or security against misuse.
