New Delhi: US Ambassador to India Eric Garcetti on Tuesday lauded National Security Advisor Ajit Doval, calling him an "international treasure".

Highlighting Doval's humble origins as a village boy from Uttarakhand, the envoy said, "India's NSA has not only become a national treasure but an international treasure".

The envoy also expressed admiration for the strong foundation between the United States and India.

"When I look at the foundation between the United States and India, it is so strong, it is so clear that Indians love Americans and Americans love Indians," Garcetti said at the United States-India initiative on Critical and Emerging Technologies (iCET) meet in Delhi.

Praising India's advancements in digital payments and financial technology, the US Ambassador said: "When I look at digital payments and financial technology that India has, we have rocked the world. A 'tea wala' in a village makes sure that she gets direct payment from the government on her phone, a 100 per cent of each one of those rupees."
