China said Tuesday it would “fight to the end” and take countermeasures against the United States to safeguard its own interests after President Donald Trump threatened an additional 50% tariff on Chinese imports. The Commerce Ministry said the U.S.‘s imposition of “so-called ‘reciprocal tariffs’” on China is “completely groundless and is a typical unilateral bullying practice.” China, the world's second-largest economy, has taken retaliatory tariffs and the ministry hinted in its latest statement that more may be coming.
