London (CNN Business) 1. US investigates Nissan: Questions over Nissan's reporting of executive pay have spread to the United States.

Nissan made the comment in relation to a Bloomberg report, which said the American regulator is looking into whether the company accurately disclosed its executive pay in the United States.

Nissan shares in Tokyo, which had been in positive territory earlier on Monday, fell following the Bloomberg report and closed down 0.8%.

2. Weak China data: Chinese industrial profits declined in December for a second month running, adding to evidence that the world's second biggest economy is weakening.

Profits declined 1.9% from the previous year in December, an increase from a drop of 1.8% in November. The data showed that profit growth slowed to 10.3% in 2018 from 21% in 2017.

Nomura analysts said industrial profits are likely to drop further due to weakening demand, falling inflation and a decline in credit.

"We expect more aggressive policy easing measures in coming quarters, as economic growth likely slows further in [the first half of the year]," they wrote in a note to clients.

Chinese manufacturing data for January will be published later this week.
