Siemens UK has warned Britain's decision to leave the European Union could have a negative impact on future investment in the country.
The group, which manufactures high-value items such as gas turbines and MRI scanners, said it remained committed to invest in its UK operations, although chief executive Juergen Maier indicated there were concerns over future investments.
"We are concerned about what the future might hold in terms of new investments that we might want to make," he was quoted as saying by the BBC.
"Short term, in terms of any investment decisions you want to make here, especially those that result in exporting to the EU, they will be on ice. No question about that."
Siemens UK, which employs approximately 14,000 staff across 13 sites, recently put on hold plans to export wind turbine blades from a new £310m ($412m, €370m) facility in Hull, which is set to employ 1,000 people.
Maier explained that while the investment was safe and the construction of the new facility will go ahead as planned, plans to export from the venue were now on hold.
"That's the opportunity that at the moment is not as clear," he said.
The 56-year-old, who backed the Remain campaign at last month's EU referendum urged the government to secure a favourable trade deal with its European counterparts following the Brexit vote.
"We've got to make sure we end up in a situation where our relationship is strong and friendly with the EU while accepting the democratic vote that we wont be [...] in the EU directly itself."
However, he insisted Britain remained an attractive place to do business, as the German giant looked to extend its 170-year long relationship with the UK.
"We are not going to run away from the British market," he said. "We are committed here. It's a great market."
