The Prime Minister said that since President Xi Jinping came to power, over 400 big names and powerful people have been convicted of corruption and that is the number one area which he hoped to learn during the China tour.
Nevertheless, China insisted it would not let Pakistan down.
Agreements pertaining to poverty alleviation in Pakistan, strengthening cooperation in agriculture and industrial sectors and technical training were signed by the two sides.
Meanwhile, the bus service is an attempt to bolster trade ties and increase friendship between Pakistan and China, but the issue revolves around the bs route that passes through PoK, where the CPEC passes, as reported by The Indian Express.
While Commerce Minister Dawood told the Financial Times that some of the CPEC agreements were unfair to Pakistani companies and should be put on hold for a year, Railways Minister Rasheed said that Pakistan wants to cut the size of the Dollars 8 billion Karachi-Peshawar rail line, the biggest project of the CPEC, by USD 2 billion.
"The Chinese side will continue to provide support and help to the best of its ability for Pakistan's economic and social development and national construction", China's Foreign Ministry cited Wang as saying, without giving details.
Pakistan and China have dismissed India's protest over the proposed luxury bus service between the two countries.
The prime minister emphasised that President Xi's vision of connectivity - Belt and Road, and its flagship project CPEC, would translate into a win-win for shared prosperity in the region and beyond.
In a meeting with Chinese IDCPC Minister Song Tao in Beijing, he said such exchanges would ensure that the exceptional friendship between Pakistan and China endured from generation to generation.
"We have very special relations with China". "These relations have not only benefited the two all-weather strategic partners but the region and world".
China Thursday sought to defend the proposed bus service with Pakistan through PaK, saying its cooperation with Islamabad has nothing to do with the territorial dispute and will not change its principled stance on the Kashmir issue.
The premier is accompanied by Bakhtiar, Foreign Minister Shah Mahmood Qureshi, Finance Minister Asad Umar, Railways Minister Sheikh Rashid Ahmed, Adviser to the Prime Minister on Commerce, Industry and Investment Abdul Razzak Dawood, and Chief Minister of Balochistan Jam Mir Kamal on his trip to China.
Earlier, President Xi warmly welcomed Prime Minister Khan and his delegation upon their arrival at the Great Hall of the People. The CPEC has also become a major irritant in India-China relations with New Delhi voicing its opposition to the infrastructure project as it traverses through Pakistan-occupied Kashmir.
They also reaffirmed their steadfast commitment to strategic partnership and underscored taking it to new heights.
PM Khan was received at Beijing Airport by China's Minister for Transport Li Xiaopeng, Ambassador to Pakistan Yao Jing, and other senior government officials.
The two foreign ministers discussed building the bilateral relationship further along the lines of the 10-point agenda covering multifaceted practical cooperation.
