Samsung says sales of the Note 7 in affected markets including the US - but not China - would resume after it deals with replacements. That process is expected to begin in about two weeks.

It will extend refund periods for affected customers and offer exchanges for other Samsung phones, says Koh Dong-jin (pictured), head of Smsung's smartphone business, at a briefing in Seoul.

Analyst Jay Yoo at Korea Investment & Securities comments: "I am concerned more about a potential reduction in sales than recall costs. The recall is likely to be a blow to earnings."

The failure of Hanjin - the world's seventh-largest shipping company - comes during the industry's busiest season.

Caterpillar it is considering closing its plant in Belgium and making 2,000 workers redundant as the US heavy equipment maker plans global job cuts amid lower demand, the AFP news agency reports, citing union leaders.

The firm, famed for its iconic yellow diggers, is said to be contemplating moving production from its sole plant in Gosselies, Belgium to one in Grenoble, France and other manufacturing sites outside Europe.

Some 1,300 jobs were cut in 2013 at the plant near Charleroi airport, south of the Belgian capital Brussels.

China's Ministry of Commerce is reviewing a proposed merger of the Chinese operation of Uber with its locally-based ride-hailing rival Didi Chuxing, reports BBC World Service. 

In August, Uber and Didi announced they would combine their Chinese businesses, creating a $35bn (£26.3bn) company that would dominate the growing Chinese market. Anti-monopoly regulators from the Commerce Ministry will examine whether the agreement protects consumer interests. 

The Uber-Didi deal also gives each company a stake in the other's global interests.

The UK's construction industry seems to have recovered in August from a downturn that started just before June's Brexit, according to a survey.

The latest Markit/CIPS UK Construction Purchasing Managers' Index rose to 49.2 from 45.9 in July, although the figure is still below 50 mark that divides expansion from contraction.

The construction survey follows a surprisingly upbeat manufacturing PMI on Thursday, which could prompt the Bank of England to rethink the need to cut interest rates again.

"The downturn in UK construction activity has eased considerably since July, primarily helped by a much slower decline in commercial building," said Tim Moore, senior economist at survey compiler Markit.
