China says Trump's 'Chinese virus' tweet smears China

China's foreign ministry said on Tuesday that U.S. President Donald Trump's tweet calling the coronavirus a "Chinese virus" smears China and said Beijing strongly opposes Trump's usage of the words.

Foreign ministry spokesman Geng Shuang told reporters during a daily briefing that the U.S. should first take care of its own matters.

The United States will be powerfully supporting those industries, like Airlines and others, that are particularly affected by the Chinese Virus. We will be stronger than ever before!— Donald J. Trump (@realDonaldTrump) March 16, 2020
