With India’s prime minister, Narendra Modi, visiting Washington tomorrow and Monday, the Atlantic Council has issued one of its memos to the president. “An Historic Opportunity to Partner with India” recommends President Donald Trump extend three vital capabilities to India. The memo highlights that this visit is his best opportunity for the United States to partner with India to deal with the major challenges facing the region, specifically those posed by China’s increasingly aggressive behavior.

According to the memo, Modi “hopes to forge a strong personal chemistry” with Trump, “and a robust security relationship, particularly by increasing defense trade, with the United States.”

India is concerned about China’s activities in the South China Sea and about China’s efforts to establish itself as an economic superpower across Asia, the Middle East, Africa, and even Europe and the Indian Ocean region.

“As naval powers, the United States and India must have unfettered access to international sea lanes that Beijing intends to restrict and control,” says the memo. “Thus, a closely coordinated US-India policy toward China is imperative.”

Another concern for India is Trump’s stated desire to return outsourced information technology services to the US, which would cost India economically. “Such policies would also pose a hindrance for bilateral trade and impede further cooperation. While appealing in the short term,” warns the memo, “such policies may inflict greater long-run costs to US security interests.”
