Newly inaugurated U.S. President Donald Trump is pushing to "take back" the Panama Canal, the world's second busiest interoceanic waterway.

US senators heard sharply different analyses about Chinese influence over the Panama Canal on Wednesday, with some experts suggesting solutions ranging from enhanced trade partnerships to military intervention to regain control of the strategic waterway.

The new administration's immigration crackdown is likely to be among the top issues during talks, but US President Donald Trump's claim that the Central American nation had ceded control of the Panama Canal to China will also loom large.
