Xi, who will travel to Pakistan on a two-day visit from Monday after a series of postponements, has decided to go ahead with the ambitious project despite serious security concern in its restive Muslim-dominated Xinjiang province as well as the Taliban threat in Pakistan.
The corridor, regarded as the biggest connectivity project between the two countries after Karakorram highway built in 1979, is a centerpiece of China's ambitions to shorten the route for its energy imports from the Middle East.
His visit to Pakistan takes place ahead of Prime Minister Narendra Modi's tour to China slated for middle of next month.
"It is yet another diplomatic action taken by China's top leader in China's neighbourhood. It will map out a plan for China-Pakistan relations and cooperation in various areas in the next five to ten years and take bilateral relations to a new level," Liu said.
Once ready the ships could offload at Gwadar, which is located just outside the mouth of the Persian Gulf, and transport the energy products to China through the pipeline network, reducing the distance by about 12,000 kms.
Providing an outline of the project, Liu played down India's concerns that it is being laid through the PoK and said that it is a commercial project.
"The project between China and Pakistan does not concern the relevant dispute between India and Pakistan. So I do not think that the Indian side should be over concerned about that," he said replying to a question.
Xi will visit Islamabad on way to Indonesia to take part in the Bandung Conference.
His trip to Pakistan was put off last September when he visited the Maldives, Sri Lanka and India and later he skipped the March 23 Pakistan National military parade where he was reportedly invited to be the chief guest.
