European countries are boosting relief efforts in their Caribbean territories devastated by Hurricane Irma, amid criticism over the response.
French President Emmanuel Macron, who is visiting French islands that took the full force of the storm, said a huge "airlift" was bringing more aid.
UK Foreign Minister Boris Johnson is due in the region and the king of the Netherlands is touring Dutch islands.
Irma killed at least 23 people in the three countries' overseas territories.
The victims include 10 dead on the French island of St Barts and on the French part of St Martin - which is shared with the Netherlands.
As he arrived in the region on Tuesday, President Macron said the government had responded with "one of the biggest airlifts since World War Two".
He told reporters that last week's hurricane had been almost unprecedented and that the effort had been hampered by a second hurricane, Jose, in the area days later.
He promised to "shake up all the rules and procedures" to rebuild the islands "as quickly as possible". Later on Tuesday he saw for himself the damage in Saint-Martin.
