Accrording to the Electronic Times, Samsung might stop producing mobile phones this year at Tianjin Samsung Telecom Technology, located in the northern Chinese city of Tianjin.

The world’s biggest smartphone maker said on Monday that nothing had been decided on the fate of its Tianjin operation.

“The overall smartphone market is having difficulties due to slowing growth. Samsung Electronics’ Tianjin telecom enterprise aims to focus on activities that increase competitiveness and efficiency”, it said in a statement to Reuters.

Just five years ago, Samsung had 20 percent of the Chinese market only to see that fall to less than one percent this year, outgunned by Huawei , Xiaomi and other Chinese brands, particularly on pricing.

Samsung has focused its major mobile phone investments on production facilities in Vietnam and India. It opened the world’s biggest smartphone factory outside New Delhi last month, which is slated to become an export hub.

According to the Electronic Times, its Tianjin plant in China produces 36 million mobile phones a year and its Huizhou plant makes 72 million units a year, while the two factories in Vietnam combined make 240 million units a year.
