NEW DELHI - India's new rules for foreign investment violate WTO principles of non-discrimination and are against free and fair trade, a Chinese embassy spokesperson in New Delhi said on Monday.

On Saturday, India stepped up scrutiny of investments from companies based in neighbouring countries, in what is widely seen as a move to stave off takeovers by Chinese firms during the coronavirus outbreak.

"The impact of the policy on Chinese investors is clear," spokesperson of the Chinese embassy Ji Rong said in a statement.

India's trade ministry said in a notification dated April 17 the changes to federal rules on investment were meant to curb "opportunistic takeovers/acquisitions". It did not mention China.

China hopes India will revise 'discriminatory practices', treat investments from different countries equally, the spokesperson said.
