The PLA stations between 500 and 600 troops in Macau, primarily as a symbolic presence to underscore Chinese sovereignty. The remainder of the 1,200-strong Macau garrison resides just across the Chinese border in Zhuhai.
Although the Macao Basic Law states that the Macau SAR government may "when necessary" ask the central government to allow the garrison to assist in maintaining public order or disaster relief, Chief ExecutiveEdmund Ho has said that, in keeping with the Basic Law the garrison will play no role in internal security. The garrison has maintained a low profile, with soldiers generally wearing civilian clothing when off base and not engaging in business activities.
Mission
According to the Law on Stationing Troops in the Macau Special Administrative Region (or Macao Garrison Law, passed by the NPC Standing Committee on June 28, 1999), the mission of the PLA in Macau is to defend the special administrative region by "preventing and resisting aggression; safe-guarding the security of Macau; undertaking defense services; managing military facilities; and handling related foreign military affairs." The PLA can also be called upon by the chief executive to help maintain public order and assist with disaster relief efforts. The members of the garrison are mainly ground force troops.
2017 Typhoon Hato
At the request of Macau SAR Government, the PLA Macao Garrison was deployed to assist in disaster relief and cleaning up in the aftermath of Typhoon Hato in August 2017, the first time for domestic affairs in Macau history. About 1,000 troops were called in to help remove debris and clear roads.
The garrison was temporarily stationed at the 11 storey Edificação Long Cheng/Long Cheng Mansion. It is now stationed on Taipa located amongst the new casinos in Cotai (Estrada da Baía de Nossa Sra. da Esperança across from Hotel Venetian and Galaxy Macau).
There are more troops at the barracks in Zhuhai (Zhengling).
