"China supports Pakistan in continuing to get to the full bottom of what happened and hunting down and bringing to justice all the perpetrators," she said.
On March 26, a suicide assault murdered five Chinese engineers and a Pakistani driver.
According to Pakistani officials, they were on their way to work at the country's largest dam in Dasu, Khyber Pakhtunkhwa. A suicide bomber drove a car loaded with explosives into their convoy.
Pakistan accuses Afghanistan of serving as a launchpad for terrorists attacking Pakistan, a claim that the Taliban has consistently refuted.
According to Islamabad, the suicide bomber who targeted the Chinese engineers was Afghan.
"The attack on the Chinese engineers at Shangla (Khyber Pakhtunkhwa) is not the only attack. There are several attacks that are carried out by Afghan nationals in Pakistan, their dead bodies were there, and they were identified as Afghans," Abdullah Khan, an Islamabad-based researcher for the Pakistan Institute of Conflict and Security Studies, told VOA.
Mounting security risks have forced Pakistani officials to implement security standards requiring Chinese nationals' home addresses and details about their mobility.
Baloch separatist organizations and Islamist terrorists have targeted Chinese interests and troops in Pakistan's resource-rich southern Balochistan and northwestern Khyber Pakhtunkhwa provinces.
Militants affiliated with Baloch separatist organizations have claimed previous assaults on Chinese nationals and interests.
