Zhang Yang, a businessman from Chongqing in southwest China, is searching online forums for fellow stout-hearted entrepreneurs willing to cast aside security concerns and join him on a scouting mission to Pakistan. Zhang, 48, is one of a growing number of Chinese pioneers sensing an opportunity across the Himalayas in Pakistan, where Beijing has pledged to spend $57 billion on infrastructure projects as part of its “Belt and Road” initiative. Numbering in the thousands, this second wave of Chinese arrivals are following in the wake of workers on Belt and Road projects. Some are opening restaurants and language schools, while others are working out what products they could sell to a market of 208 million people, or what goods they could make cheaply in Pakistan to sell around the world.
