Baluchistan is the site of several Chinese infrastructure projects, the biggest being a Chinese-operated deepwater port in Gwadar.
China is estimated to have spent around $62 billion on the so-called China-Pakistan Economic Corridor, an investment that is part of China’s Belt and Road Initiative, a $1 trillion chain of infrastructure development programs stretching across around 70 countries.
Since the initiative began in 2013, Pakistan has served as its flagship site, with China using the partnership with its strategically located and nuclear-armed neighbor to advance its own military and economic interests.
Its plan for Gwadar includes a large special economic zone for Chinese companies.
Baluchistan is also viewed by Pakistani officials and some analysts as the scene of shadowy proxy wars between regional and international powers, including India and Iran.
In Saturday’s attack, after entering the hotel, the gunmen exchanged gunfire with security forces. Officials said they had evacuated most of the hotel’s occupants, and security forces had cordoned off the hotel. Still, the attack was seen as a major security breach because Gwadar has a large presence of security forces.
The Zaver Pearl Continental is on a hill overlooking the Arabian Sea, and Mr. Butt, the police official, said that the gunmen may have come by boat.
Baluchistan — a sparsely populated province rich in gold, copper and natural gas — borders Afghanistan and Iran. Ethnic Baluch separatists, demanding greater autonomy and rights, have clashed with security forces in a long-simmering insurgency there.
