LUXEMBOURG, April 24 (Reuters) - Recent remarks by China's ambassador to France questioning the sovereignty of former Soviet states such as Ukraine are totally unacceptable, several EU foreign ministers said before a meeting on Monday. "It is totally unacceptable", Czech Foreign Minister Jan Lipavsky said ahead of the Luxembourg meeting of the bloc's foreign ministers. It was unclear when Fu Cong, the Chinese ambassador to the EU, gave the interview to the Chinese news outlet The Paper. But its publication came hard on the heels of the remarks by China's ambassador to France. Italian Foreign Minister Antonio Tajani said he disagreed with Lu's comments, while Luxembourg's foreign minister Jean Asselborn called Lu's remarks a "blunder" and said efforts were being made to calm things down.
