Thailand has delayed plans for a "travel bubble" agreement with select countries as the number of novel coronavirus cases reported daily rises in parts of Asia, putting pressure on its vital tourism industry and complicating efforts to revive its battered economy.

Thailand first proposed the idea in June, to allow movement between select countries that have low infection numbers without the need for travelers to undergo quarantine.

But it has been shelved, officials said, amid second and third waves in East Asian countries that previously had their outbreaks under control.
