China firmly rejects any form of official US and Taiwan contact, foreign ministry spokesman Zhao Lijian told a regular news briefing.
On another matter, aiwan's exports rose for a ninth straight month in March, and far exceeded expectations, as global demand for microchips and hi-tech gadgets remained strong in the work-from-home Covid-19 pandemic boom.
Exports rose 27.1% from a year earlier to $35.89 billion in March, the Ministry of Finance said on Friday, the highest monthly figure on record.
Analysts in a Reuters poll had forecast a rise of 17.4% for March, compared with a 9.7% increase in February.
The ministry attributed the growth to a return of economic confidence as countries around the world roll out vaccination programmes, and to continued strong demand for tech products to support remote working and the "home economy".
Firms such as Taiwan Semiconductor Manufacturing Co Ltd (TSMC) are major suppliers to Apple Inc and other global tech giants, as well as providers of key chips for auto companies and lower-end consumer electronics.
Beatrice Tsai, head of the ministry's statistics department, told reporters that TSMC, the world's largest contract chip manufacturer, would be running at full capacity until the end of next year.
TSMC declined to comment ahead of its first quarter earnings next week. It said this month it plans to invest $100 billion over the next three years to increase capacity at its plants.
The move comes as global companies reel from a shortage of semiconductor chips that initially forced automakers to cut production, but is now hurting some makers of smartphones, laptops and even appliances amid a pandemic-fuelled rise in demand. - Reuters
