Chinese Say They're Building 'Impossible' Space Drive

They are right: no law is broken. There are wrong: not broken laws mean no net thrust.

The theory is based on an implicit doubtful assumption: Newton’s Second Law should not apply between the wave and the dielectric section or the walls. Why?!
It is stated that "the reflection-free interface (vacuum/dielectric), with matched wave impedances, will ensure no forces are produced at the interface". Right but it is only a part of the problem. The wave entering the dielectric and the dielectric slowing the wave, it is obvious that, due to the conservation of momentum, the wave imparts a force pushing the dielectric towards the direction of the wave. If there is no dielectric, similar reasoning applies: the walls of the wave guide reducing the cross-section, a force will be acting onto the walls.   
We guess this forces will balance the expected "no reaction" force.

No, it's just the fact that Newton wrote his laws with the left hand, and now they have become a dogma

Both USA and the Russians found out as early as the 50's that Newton's so-called 'laws' are no such thing - the US with the Explorer missions, the Russians, after sending their first probe to the moon.  The Explorer rocket performed nothing like Newtonian mechanics predicted, whereas the Russians missed the moon completely with their attempt!  After multiple incarnations of the Explorer rocket, Von Braun finally figured out the problem - spinning objects do not behave the same as non-spinning objects in a gravity field, and since Newtonian machanics makes no distinction between the two, (ie a torsion element) it is essentially useless in predicting spinning bodies!  Incidently, both the Explorer and Russian rockets were 'spun up' in order to average-out variations in the burn-rate of the different solid rocket boosters, Explorer 'manually' to about 500 rpm, while the Russian rockets employed high-speed gyroscopes which ellegedly contributed to similar 'Newtonian in-accuracies' the Americans were experiencing.  The American solution was to develop a non-spinning rocket, which were the Ranger missions, while those clever Russians apparently did something similar, as their next moon probe was spot-on!

Point is, Newtonian mechanics have been known to be practically useless in some instances (therefore, certainly not "Laws") for more than half a century, yet interestingly, this major breakthrough has never been made known publically in the interim - the reason, according to Hoagland, is that it would lead to inventions such as anti-gravity etc.
