科伦坡港口城是斯里兰卡目前最大的外国投资项目，位于首都科伦坡核心商贸区，通过在科伦坡港口附近填海造地的方式，建造一个由高尔夫球场、酒店购物中心、水上运动区、公寓和游艇码头在内的港口城。该项目由中国交通建设股份有限公司与斯里兰卡国家港务局共同开发。该项目并非两国的政府间项目，而是公私合营的投资项目，即由斯里兰卡政府负责环境、规划和施工许可，中国企业负责投资、规划、施工和运营。按最初计划，该港口城规划建筑规模超过530万平方米，工程直接投资14亿美元，为斯里兰卡创造超过8.3万个长期就业岗位。该项目工程于2014年9月17日开工，后因斯里兰卡大选以及政府更迭等因素影响，建设有所延宕。经中方多方面交涉，在2016年8月签署新的三方协议后，该工程项目得以继续推进。
