A car bomb blast outside a luxury hotel where the Chinese ambassador was reportedly staying in the southwestern Pakistani city of Quetta has killed four people and injured 12, according to local authorities.
Balochistan’s provincial Home Minister Ziaullah Lango told reporters that Mr Nong was “in high spirits” and that his visit to Quetta would conclude on Thursday.
One of Pakistan’s poorest provinces, Balochistan is home to several armed groups, including Islamic extremists and separatists.
Militants want independence from the rest of Pakistan, and oppose major Chinese infrastructure projects in the area.
The separatists were also blamed for an attack two years ago on a hotel at Gwadar, a port project funded by China.
They accuse the government and China of exploiting Balochistan’s gas and mineral wealth, and strategic position with little benefit to local people.
