The private sectors from India, the US and Japan have a key role to play in the development of infrastructure in the Indo-Pacific which has "vast opportunities" for the companies of the three countries to be the "pioneers" in the region, a senior American diplomat has said. Acting Deputy Assistant Secretary for South Asia Thomas Vajda said the private sector played a central role in developing the connectivity and networks that promote prosperity. Vajda welcomed the recent initiative of US Chambers of Commerce to create Indo-Pacific Infrastructure Trilateral Forum, which brings together private sector companies from India, the US and Japan for building infrastructure in the region. "In addition to the work of governments, it is essential to remember the central role the private sector plays in developing the connectivity and networks that promote prosperity and bring us closer together," Vajda told PTI. "There are vast opportunities for our companies to be pioneers in this area," he said after US India Business Council (USIBC) and US Japan Business Council (USJBC) \u2013 the two international wings of US Chambers of Commerce - launched Indo-Pacific Infrastructure Trilateral Forum early this week. "We are grateful that USIBC and USJBC are leading the charge by hosting engagements such as the Indo-Pacific Infrastructure Trilateral Forum, which help support quality, best value, and sustainable infrastructure development in the Indo-Pacific region," he said. As one of the primary architects of the region's security and economic systems, the US has a strong interest in seeing the Indo-Pacific continues to thrive, Vajda said.
