China and India will discuss the US' trade war and its protectionist trade policy when President Xi Jinping and Prime Minister Narendra Modi meet on the sidelines of the BRICS Summit in Johannesburg next week, the Chinese Foreign Ministry said on Friday.

While China is locked in a trade war with the US, which accuses Beijing of dodgy business practices, New Delhi last month decided to hike tariffs on 30 US products in retaliation to American President Donald Trump's decision to slap more taxes on Indian steel and aluminium.
