Although Nanjing in East China's Jiangsu Province is tense after being fully mobilized on a "wartime" footing to battle against imported coronavirus cases, the city -- home to many world-leading electronics companies -- is operating "basically normal".

A director of China Electronics Corp, a state-owned company with a factory in the city's economic and technological development zone, said that there has been no substantive impact. The person told the Global Times on Thursday that all employees had taken nucleic acid tests and been vaccinated, and they are now on flexible work shifts.

All employees are living in the factory compound and have little contact with the outside, further minimizing the risks of infection, he said.

A manager with a foreign electronics company told the Global Times that it is cooperating with overall nucleic acid testing and screening, with no impact on business operation. All the staffers are working on-site except for a few who had been to Lukou airport and are now under home quarantine. There's been little impact on production, but logistics have become a hurdle.

Traffic controls have been tightened with domestic, international and regional flights out of Nanjing all canceled until August 11.

Because of the measures, logistics services have been delayed, which means just-in-time deliveries for goods are impossible, an employee with a large board-making company told the Global Times on condition of anonymity.

The company has talked with its domestic and overseas clients and gained their understanding.

Despite the outbreak in Nanjing, industry insiders said that the city's status in the domestic electronics production supply chain, which developed over many years, would be not shattered easily. High levels of automation on production lines are also helping.

But experts said that if the outbreak worsens, logistics hurdles could pose further disruption to businesses.
