Businesses and analysts predict that the coup in Myanmar is likely to damage the country's economy.
Companies say the coup has already put billions worth of foreign investment at risk.
The US has already said it is considering imposing additional sanctions on Myanmar, which is one of the region's poorest countries.
However, the impact of US sanctions could be limited because most of the country's investment comes from Asia.
According to the World Bank, Singapore was the largest foreign investor in Myanmar last year, accounting for 34% of overall approved investment. Hong Kong was the second largest investor with 26%.

Foreign Direct Investment (FDI) commitments into Myanmar were worth $5.5bn (£4bn) in the 2020 fiscal year, which ended in September slot pg .
Real estate and manufacturing each accounted for about 20% of that figure.
These figures were already expected to be significantly lower this year due to the Covid-19 pandemic.
Will China be the winner?
Vriens & Partners is a government affairs consultancy that is currently handling $3bn-$4bn worth of projects for foreign clients investing in Myanmar.
The projects are mainly for energy, infrastructure and telecommunications.
"That's all at risk now," said the firm's managing partner Hans Vriens.
"This country has already been badly hit by Covid and by diminishing appetite to invest. And now we have this on top."
Sanctions could have a significant effect on foreign investment, with both Western and Japanese companies thinking twice about projects in Myanmar.
With the US already considering sanctions against Myanmar, Mr Vriens thinks businesses might turn to China instead.
"It's really the only country they can turn to," he said.
