A Mexican race official has said that he hopes his colleagues north of the border can end the uncertainty surrounding the 2016 US Grand Prix.

A government funding dispute has thrown the popular Austin race, currently listed as "subject to confirmation" on the final 2016 calendar, into doubt.

It is provisionally scheduled to be the first in an American 'double header' this year, with Mexico taking place on the following weekend, in late October.

Earlier, it was planned that some cross-promotional activities between Mexican and US organisers would be shared.

However, Mexico's F1 marketing director Rodrigo Sanchez told Sports Business Daily Global: "[Circuit of the Americas] are going through a lot right now, and there's a lot of stuff that they need to prioritise before even thinking about things like how to cross-promote events.

"Hopefully they can get their things together and host another successful grand prix in the States."

The US Grand Prix is provisionally listed for October 23.
