Panama Canal's neutrality benefits the world

China's permanent representative to the United Nations, Fu Cong, has rejected US accusations over China's role in the Panama Canal. 

At a Security Council meeting, Fu said China has always respected Panama's sovereignty over the canal and its neutrality as an international waterway. 

The US under President Trump, on the other hand, has repeatedly threatened to re-take control of the canal, sparking confusion and shock in Panama. Alasdair Baverstock reports.
