Apple's China warning 'deflects deeper problems' for firm Image copyright Getty Images A shock revenue warning from Apple has stoked fresh fears about trade tensions and spending in the world's second largest economy.
But analysts say the cut to its sales forecast reflects longstanding problems at the tech giant.
iPhone sales have been sliding and Apple faces stiff competition in China.
Experts argue the warning highlights the company's need to create new centres of growth.
In a letter to investors on Wednesday, Apple's chief executive Tim Cook said China was central to Apple's sales problems.
The Greater China region, which includes Hong Kong and Taiwan, accounts for almost 20% of the firm's revenue.
Mr Cook said Apple "did not foresee the magnitude of the economic deceleration" in Greater China, adding that US-China trade tensions had hurt consumer confidence.

Abby Sunderland: Yacht abandoned in 2010 record attempt found Image copyright SA Police Image caption The 40-foot vessel Wild Eyes was found upturned and covered in barnacles Almost nine years after being abandoned in the Indian Ocean, a yacht belonging to a teenage round-the-world sailor has turned up off southern Australia.
US girl Abby Sunderland was aged 16 in 2010 when she attempted to become the youngest person to circumnavigate the globe, but a storm crippled her vessel.
She was rescued more than 3,220km (2,000 miles) from the coasts of both Africa and Australia.
The yacht was spotted on Monday, upturned and covered in barnacles.
It was reported to authorities by a tuna-spotting plane about 10km south of Kangaroo Island, a popular tourist destination in South Australia, police said.
"My heart skipped a beat," Ms Sunderland said in a statement reported by Australian media.
"It brought back many memories - good and not so good - but it was neat to see it after so long. It looked ..
Planet satellites get clear view of Anak Krakatau volcano Image copyright Planet Labs, Inc. Image caption Anak Krakatau as it looked on New Year's Day. Planet's constellation maximises the chances of getting a cloud-free view There is now some very good optical satellite imagery of the collapsed Anak Krakatau volcano, which generated the devastating tsunami on 22 December.
Poor weather conditions over Indonesia's Sunda Strait had frustrated spacecraft that view the Earth in the same type of light as our eyes.
But the team at Planet has managed to find windows in the cloud.
Pictures from its Dove and SkySat platforms show the extent of the volcanic cone's failure.
It is easier to appreciate now how the island has been reshaped.
What was once a crater at the summit of a 340m-high edifice has been completely broken open to form a small bay.
Indonesia's disaster agency says more than two-thirds of Anak Krakatau's volume (150-170 million cubic metres) is missi..
What it's like to work in an Indian 'rat-hole' mine Image copyright Priyanka Borpujari Image caption Abdul Alim has worked in rat-hole mines for two years Fifteen men have been trapped inside a so-called rat-hole mine in India's north-eastern state of Meghalaya since 13 December. Priyanka Borpujari spoke to a miner who left his job at the same mine days before the accident because he found it to be too dangerous.
Abdul Alim believes if he had stayed, the job would have killed him.
Two cousins, Omor and Shirapat Ali, are among the 15 miners who have been trapped for three weeks.
Abdul, who fears they may be dead by now, stutters every time he speaks about them.

Australian police respond to spider death threats Image copyright Getty Images Image caption Australia is home to over 2000 species of spider, many of them venomous A man with a "serious fear" of spiders prompted an emergency call by Western Australia police on New Years' Day.
According to police, a passerby raised the alarm after hearing a "screaming" toddler and a man repeatedly shouting "Why don't you die?"
But after arriving at a home in suburban Perth, they found the man had merely been trying to kill a spider.
In a tweet, police said there had been no injuries during the incident - "except to spider."
"It's just one of those jobs where you go expecting to see one thing and see another," police spokesman Samuel Dinnison told the BBC.
"It's great that it's only an incident involving a spider."

Apple blames China as it cuts forecast Image copyright Getty Images Apple has warned investors about its growth in the most recent quarter, citing weaker sales in China.
In an unexpected disclosure, the iPhone maker said it expected revenue of about $84bn (£67bn) in the three months to 29 December.
That is down from its November forecast of at least $89bn - a prediction that had already disappointed investors.
The firm's shares have already fallen more than 28% since it offered investors that November outlook.
In a letter to investors on Wednesday, chief executive Tim Cook said the firm's miss was due primarily to its Greater China region, which includes Hong Kong and Taiwan and accounts for almost 20% of its revenue.
"While we anticipated some challenges in key emerging markets, we did not foresee the magnitude of the economic deceleration, particularly in Greater China," he said.
"In fact, most of our revenue shortfall to our guidance, and over 100% of our year-over-year ..
Cathay Pacific to honour $16,000 fares sold for $675 Image copyright Getty Images Cathay Pacific has said it will honour first-class and business-class tickets that it sold to some lucky passengers for a fraction of the usual price.
The Hong Kong-based airline mistakenly sold business-class seats on August flights from Vietnam to New York for about $675 return.
Prices on the same route in July and September cost $16,000.
The airline admitted that it "made a mistake", but said it would honour the tickets.
The fares were reported by travel bloggers on 31 December and later pulled by Cathay Pacific.
It was not clear how many tickets had been sold and Cathay Pacific did not immediately respond to requests from the BBC.
