Cambodia gets its own chapter in IAM Patent 1000 for the first time, following several government initiatives to promote innovation. Over the past few years, the country has entered into patent cooperation agreements with Japan, Singapore, Europe, China, South Korea and, most recently, signed a memorandum of understanding with the United States. The Cambodian economy was hit hard by the covid-19 pandemic but is expected to recover and continue its path of growth in 2021.
