Estonian media reported on Tuesday that China's ambassador to Estonia, Guo Xiaomei, told a meeting with chairman of the Estonia-China parliamentary group Toomas Kivimagi that she may leave the country if Taiwan opens such an office.

"China urges the Estonian side to abide by its solemn commitment to the one-China principle, refrain from allowing Taiwan to set up any official organisations and effectively safeguard the political basis of bilateral relations," ministry spokesperson Wang Wenbin told a regular press briefing.

Taiwan's Foreign Ministry said last week that it was still in the discussion phase about setting up a representative office in Estonia and that the two sides had not yet reached consensus on the matter.

Taiwan Foreign Minister Joseph Wu is visiting the three Baltic states of Estonia, Lithuania and Latvia this week. Taiwan already has representative offices in Latvia and Lithuania.

China claims democratically-governed Taiwan as its own territory, which Taiwan's government rejects.
