President Joe Biden and China President Xi Jinping spoke on the phone Thursday morning as tensions between the two nations remain high.
The conversation between Biden and Xi lasted more than two hours.
When discussing Taiwan, Xi reportedly told Biden to not play with fire.
In a readout from the White House, Biden said U.S. policy has not changed and he "strongly opposes unilateral efforts to change the status quo or undermine peace and stability across the Taiwan Strait."
Adding to the tensions, the Associated Press reported on Wednesday that House Speaker Nancy Pelosi is planning on visiting Taiwan.
The U.S. does not officially recognize Taiwan’s independent status. However, mere talks of diplomatic ties between Taiwan and the U.S. could raise tensions with China.
Pelosi’s office has yet to confirm reports directly she is headed to Taiwan, but House Foreign Affairs Committee ranking member, Rep. Michael McCaul of Texas, told the Associated Press he was invited.
