Greenell said establishing railway ties became a priority after American officials brokered an agreement this week to restore air traffic between the two countries after 21 years.

President Trump's version is just happening. The business community and the focus on job creation are issues advancing”, Grenelli told the AP.

The US ambassador said the US wants both sides to focus on economic, labour and prosperity as an effective way of normalising relations.
