(NBC) Researchers who use laboratory monkeys to study human diseases are worried that President Donald Trumps new tariffs on China will damage U.S. biomedical research and send animal testing labs to China. The Trump administration is set to impose a 15 levy on $300 billion worth of Chinese imports as part of the escalating U.S.-China trade war. The first of those tariffs will go into effect Sept. 1 with the remainder imposed Dec. 15. The new tariffs are a concern for U.S. researchers who are struggling to acquire live animals in the midst of intense scrutiny from animal rights groups and continued bans by airlines on transporting them. Animal rights activists in contrast view the tariffs as a temporary victory that could slow down the imports of monkeys.
