The Chinese government had demanded Lithuania’s remaining diplomats in Beijing hand in their diplomatic IDs to the foreign ministry to have their diplomatic status lowered. The move raised concern in Vilnius that the officials could lose diplomatic immunity, putting their safety at risk if they remained in China. [1]

After Lithuania allowed Taiwan to open a representative office in Vilnius under the "Taiwan" name, and subsequently getting blocked from Chinese customs from EU shipping routes [2], and now being asked to change the ID of their diplomats to remove the diplomatic status, many would not doubt that the Chinese government would arrest and detain some embassy staff in this move, as ordinary residents of the country, like they have done in the past in the case of Canadians [3]
