The assailants were on a motorcycle when they shot at the Chinese nationals in Pakistan's Karachi

Two Chinese nationals were fired at by unidentified assailants on a motorcycle in Pakistan's Karachi on Wednesday. Both of them have been shifted to a civil hospital in Karachi.

Speaking on the incident, Chinese foreign ministry spokesperson Zhao Lijian called the incident "an isolated case". "We have full confidence in the Pakistan side's protection of Chinese citizens and property in Pakistan," news agency Reuters quoted him as saying.

The incident comes two weeks after the IED attack on a bus carrying Chinese engineers to the Dasu dam site in Upper Kohistan in Khyber Pakhtunkhwa on July 14. At least 13 people, including nine Chinese nationals, were killed in the incident.

In April this year, a bomb exploded at a top hotel hosting the Chinese ambassador in Quetta in southwestern Pakistan, killing four people.

In 2019, gunmen stormed a luxury hotel overlooking a flagship CPEC project -- the deep-water seaport in Gwadar that gives China strategic access to the Arabian Sea -- killing at least eight people.

China is a close ally and major investor in Pakistan. A massive amount of Chinese money has been pumped into creating, training and equipping two Special Security Divisions (SSDs), the 34 and 44 Light Infantry Divisions with 15,000 troops each of the Pakistan Army.
