According to The Guardian, the US national security council (NSC) has insisted that US Speaker Nancy Pelosi "has the right to visit Taiwan", amid reports that she will be landing on the island on Tuesday – a move that China has vowed to respond to forcefully.

The market was also bolstered by gains in Plexure Group and Pacific Edge. Plexure Group, which is outside the benchmark index, again jumped 26 per cent to 41 cents after yesterday's news McDonald's has renewed its contract with the company to use its digital customer engagement platform for the next five years. That added to yesterday's 53 per cent gain.
"They are generating reasonable revenue and that revenue is expected to grow, as are their profits so that was a really positive announcement," said McIntyre.
Pacific Edge clawed back some of yesterday's losses after it said its cancer tests could be dropped by a major US health insurance company that is considering a new way to choose which tests are covered. The stock climbed 11 per cent to 54 cents.
"The company is probably going to be a bit volatile for a while," said Davies. "There are still a lot of unknowns around their ability to make revenue in [the United] States at the moment."

Wednesday's labour data will be key for investors as companies continue to struggle to find workers and are also grappling with increasing costs.
