During the state visit of Chinese leader Xi Jinping to Pakistan in April 2015, he wrote in an open editorial stating: "This will be my first trip to Pakistan, but I feel as if I am going to visit the home of my own brother." On 20 April 2015, Pakistan and China signed an agreement to commence work on the $46 billion agreement, which is roughly 20% of Pakistan's annual GDP,[1] with approximately $28 billion worth of fast-tracked "Early Harvest" projects to be developed by the end of 2018.[49][50]
