A suicide bomber rammed a vehicle into a convoy of Chinese engineers working on a dam project in northwest Pakistan on Tuesday, killing six people, police said, the third major attack on Chinese interests in the South Asian country in a week.The first two attacks targeted a Pakistan naval air base and a strategic port used by China in the southwest province of Balochistan where Beijing is investing billions in infrastructure projects.The engineers were en route from Islamabad to their camp at the dam construction site in Dasu in the province of Khyber Pakhtunkhwa, regional police chief Mohammad Ali Gandapur said.“Five Chinese nationals and their Pakistani driver were killed in the attack,” Gandapur told Reuters.Dasu is the site of a major dam and the area has been attacked in the past.

A blast on a bus killed 13 people, including nine Chinese nationals, in 2021.Chinese engineers have been working on a number of projects in Pakistan with Beijing investing over $65 billion in infrastructure works as part of the China Pakistan Economic Corridor (CPEC) under Beijing’s wider Belt and Road initiative.No one claimed responsibility for Tuesday’s attack; there also had been no claim for the 2021 attack.

Pakistan is home to twin insurgencies - one by Islamists and the other by ethnic militants seeking secession.While Chinese interests are primarily targeted by the ethnic militants seeking to push Beijing out of mineral-rich Balochistan, they generally operate in the country’s south and southwest - far from the site of Tuesday’s attack.Islamists mostly operate in Pakistan’s northwest, the area where the convoy was attacked.Khyber Pakhtunkhwa police have reached the spot and started relief operations.A separate police source told Reuters the convoy was carrying staff of the construction firm China Gezhouba Group Company (CGGC) working on the Dasu hydropower project - the same company targeted in 2021.Construction work ceased for months after that attack.China’s embassy in Pakistan demanded investigations into the attack.“The Chinese embassy and consulates in Pakistan have immediately launched emergency work, demanding that the Pakistani side conduct a thorough investigation into the attack, severely punish the perpetrators, and take practical and effective measures to protect the safety of Chinese citizens,” the embassy said in statement.The embassy on Wednesday also warned Chinese citizens to stay abreast of the situation and strengthen security measures.

It said China will work more resolutely with Pakistan to do its utmost to maintain the security of Chinese personnel, projects and institutions in Pakistan.‘FOREIGN ELEMENTS’Prime Minister Shehbaz Sharif is expected to visit Beijing next week, according to a source in the Prime Minister’s Office, his first since taking office following February elections.On Tuesday afternoon after the attack, Sharif went to the Chinese embassy to offer condolences to victims’ families and the Chinese government, the embassy said on Wednesday.A Pakistani military statement said the three attacks in the last week were aimed at destabilising the internal security situation, accusing “foreign elements” of aiding and abetting such incidents in Pakistan.It said strategic projects and sensitive sites vital to Pakistan’s economic progress were being targeted in an effort to sabotage it and sow discord between Pakistan and its allies, most notably China.Pakistan’s Indian Ocean port of Gwadar, on the route to key Gulf shipping lanes, is managed by China, while nearby naval air base Siddique is used to support security and development work, spearheaded by Beijing, in Balochistan.Both were attacked in recent days by Baloch separatists.Foreign Minister Ishaq Dar condemned Tuesday’s attack and said Pakistan would continue to fight back against militants.Pakistan’s foreign office said the life and safety of Chinese nationals in Pakistan was of paramount importance.“Pakistan will continue to work with our Chinese brothers in ensuring the safety and security of Chinese nationals, projects and institutions in Pakistan,” it said in a statement.Source: Reuters -Agencies
