“Other devices” means manually-emplaced munitions and devices including improvised explosive devices designed to kill, injure or damage and which are actuated manually, by remote control or automatically after a lapse of time.
It is prohibited to use booby-traps or other devices in the form of apparently harmless portable objects which are specifically designed and constructed to contain explosive material.
“Booby traps and other devices” is one legal thing, there’s no legal distinction. Pager bombs are always a war crime regardless of circumstances.
The second one is more like what the original razed 17th century mosque looked like. Deng was the one who gave orders to open fire in Shadian, he’s not good guy liberal here. Mao’s strategy was to yell at people to be atheist. Deng’s strategy was a religious red light district. Keep it alienated from secular society, make the mosques look like they were air-dropped from Saudi Arabia instead of having been there for 500 years, and give people the choice to be religious or Chinese but not both.
Starting before Xi China realized that wasn’t working, especially in Xinjiang, so the new strategy was to integrate. That means less of Deng’s “laugh at this weird foreign religion” architecture and more of “respect China’s history of patriots who are Chinese first and Muslim second.”
