Following a phone call with Taiwan leader Tsai Ing-wen, U.S. President-elect Donald Trump took to Twitter again to criticize China. He posted two tweets on Sunday to criticize the Chinese government about currency manipulation, tariffs and military policy.

One tweet says China is building a massive military complex in the South China Sea, while the other says the RMB devaluation makes U.S. domestic companies suffer. The tweets come on the heels of criticism of Trump over the phone call with Tsai.

Some comments say Trump now speaks for the whole country, so he should think twice before saying anything. Still, it seems that America’s next leader cannot stop talking about China. And there is little doubt that Trump will continue to pay close attention to his country’s second biggest trade partner.
