Jamaica has warned Britain it will be guilty of "vaccine politics" and unfair discrimination if it bans travel to the island nation next month.
Edmund Bartlett, its tourism minister, said the UK's new "traffic light" system for travel was "unfair" to small nations like Jamaica that had not had access to Covid vaccines.
The system for determining whether foreign travel bans are lifted from May 17 is based on countries' vaccination rates, the prevalence of Covid and its variants and capacity for accurate testing to track the spread of the virus.
But speaking at the World Travel and Tourism Council Global Summit in Cancun, Mexico, Mr Bartlett said it was a recipe for global unfairness and "disruption" and urged the UK to honour its historic Commonwealth links by sharing its vaccine supplies with Jamaica and other poorer nations.
"We lack the resources to access vaccines. I fear that vaccine politics is going to militate against smaller, poorer countries that cannot afford to have it," said Mr Bartlett.
He said 10 countries had cornered more than 70 per cent of all vaccines and were innoculating their populations at five times the rate of the rest of the world.
"That's a serious problem in terms of equity and a serious problem in terms of how the distribution of fairness goes in the global space," he said.
"If you then put in divisions, categories and travel advisories developed on the basis of whether countries are fully, partially or not vaccinated, then you are going to be dividing the world, leaving many people behind and that is a recipe for global disruption.
"If the pandemic caused a global disruption, let us not make the solution to the pandemic also a global disruptive element.
"Let us use our influences as leaders of the world to distribute this in a more equitable way. Let us stop playing vaccine diplomacy."
Jamaica fears it could be red listed under the new traffic light system having so far vaccinated just under 10 per cent of its population.
"The distribution of vaccines being as they are, the UK should have a duty to enable us to have access," said Mr Bartlett.
"If the Commonwealth is to mean something, then leaders of the Commonwealth - and we are Her Majesty's loyal subjects and [the Commonwealth] is supposed to have value - should talk about how we make sure Her Majesty's subjects all have an equal chance to survive in a pandemic."
He claimed Jamaica was the first country in the world to set up "resilient" corridors or bubbles where tourists are effectively isolated and which have meant they had the lowest infection rates in the caribbean.
"We have more than established that a bubble does work. We think we should be credited with that and to allow for tourists to come."
