Christophe Imran, a spokesman, said the company had not received orders at the stage of its supply chain, of which this was a part.

“We always try to ensure that our customers’ safety is our top priority in the supply chain,” he said.

The government shutdown has reduced China’s number of imports to just one per cent of the world’s market, Mr Imran said. This has meant that it is now less able to sell its products in the Netherlands.

But some of Ms Gonsalves’ customers are still hoping to find her in the country.

Ms Gonsalves said she had a “hunch” that her family was still waiting in Thailand and had called Ms van Woudenbergen to offer any news on where she was.

“I just hope some of the people I know from the mainland are still here,” she said.

After the Dutch media reported the Dutch police were searching for Ms Gonsalves, Mr Gonsalves told a Dutch newspaper she had told her parents they should come to Japan to watch her “special show”.

“She told them her show was called The Gonsalves Show, which was also a huge success here,” he said.

Mr Gonsalves said his family had left Thailand early last year and travelled to Singapore for treatment.

The Dutch man was diagnosed with liver cancer and was rushed to hospital, but was never pronounced clinically dead.

He underwent an operation to remove two small bowel tumours in February but the cancer had already spread to his brain.

Last week, Mrs Mertens appeared in public for the first time since Mr Gonsalves received a kidney transplant that was not related to his illness, although officials could not say why.
