"The trade sanctions that have resulted from recent disputes are hurting both countries, and I hope that they can be resolved as quickly as possible," Feinstein wrote.
Observing that trade with India has grown dramatically since 2000, Feinstein said India imported goods worth over $6 billion from California in 2018 and is a major customer of agricultural and electronic products from the western-US state.
"It is the people caught up in these trade conflicts such as California's almond and walnut producers, who were subject to recent retaliatory tariffs from India, who suffer most," she said.
The issue of trade tension came up in a telephonic conversation between President Donald Trump and Prime Minister Narendra Modi on Monday.
"Referring to their bilateral discussions in Osaka, the Prime Minister expressed the hope that the Commerce Minister of India and the US Trade Representative would meet at an early date to discuss bilateral trade prospects for mutual benefit," said the Prime Minister's Office in a readout of the call.
According to White House Principal Deputy Press Secretary Hogan Gidley, the two leaders discussed ways to strengthen US-India economic ties through increased trade.
