Apple's "China Plus One" strategy boosted India's export share, research shows.

India has overtaken China as the leading exporter of smartphones to the U.S., as Apple continues to shift production in the face of the Trump administration’s tariffs, according to new research released Monday.

The share of US smartphone shipments assembled in China fell to 25% in the April-June period, from 61% a year earlier.

President Donald Trump says the United States and India are still negotiating on trade despite new tariffs slated to begin in a few days.

The president said Wednesday that imports from India would be subject to a 25 percent tariff as of Friday, as trade talks between the countries hit a stumbling block.
