Japanese wireless carrier NTT Docomo, Sony and California-based chip giant Intel pulled out of the the MWC Barcelona trade show on Monday because of the coronavirus outbreak . Amazon.com , South Korea’s LG Electronics, Swedish telecommunications equipment supplier Ericsson and US chip maker Nvidia have already withdrawn from MWC Barcelona, which had more than 100,000 visitors and upwards of 2,400 exhibitors in 2019. MWC Barcelona, which will be held from February 24 to 27, is the mobile industry’s biggest annual gathering , with companies spending millions on stands and hospitality to fill their order books. Barcelona’s economy got a boost of around 470 million euros (US$515 million) last year from the event, according to estimates by organiser the GSM Assocation. The GSMA had no immediate comment. Gremi d’Hotels de Barcelona, the city’s main hotels association, said coronavirus concerns had resulted in cancellations, but it was too early to quantify the impact on overall bookings. China’s smartphone giants cut size of contingent to world’s biggest mobile show And the region’s digital policy councillor, Jordi Puignero, told local radio station RAC1 the Catalan regional government was “taking measures so that everything proceeds as normal”. “There is no reason to not attend,” he added. Sources close to exhibitors said that if participants cancel, they would have to bear the cost. The GSMA, an industry association representing more than 750 mobile network operators and 400 companies, would only be liable if it calls off the event. Sony and NTT Docomo said in statements they had withdrawn after taking into consideration the safety of customers, partners and staff. Sony said its launch event would be held via video. NTT Docomo did not immediately confirm whether its chief executive, Kazuhiro Yoshizawa, would continue as a panel speaker. US-Israeli software provider Amdocs also pulled out of the event on Monday. “While we appreciate the precautionary measures put into place by the (organiser) GSMA, we believe the safest option is not to attend MWC 2020 in Barcelona,” Amdocs’ chief executive Shuky Sheffer said in a statement. Chinese electronics company TCL said it was cancelling a press event, but would still attend MWC Barcelona and showcase new devices, while Norway’s Telenor said it was planning to cut the number of staff attending as well as reducing its programme. GSMA said on Sunday that no one from China’s Hubei province, where the coronavirus outbreak began, would be allowed to attend, while visitors from China must prove they have been outside the country for at least two weeks before the event. These measures add to earlier actions aimed at preventing the spread of the virus, including changing microphones between speakers and advising all attendees not to shake hands. The death toll from coronavirus in mainland China has risen above 1,000 , with more than 42,600 people infected. More than two dozen countries are grappling with the virus, which has infected 460 people outside China as of Tuesday morning. In 2019, some 6 per cent of MWC Barcelona attendees were from China, GSMA’s post-congress report showed. Most were from Europe, around 64 per cent, as were about 45 per cent of the exhibitors. China’s Huawei Technologies and ZTE Corp have said they will attend , ordering assigned staff to the event to self-isolate ahead of the exhibition’s opening and drafting in European staff to cover for those not able to attend from China.
