No. Not even in the U. S., or maybe particularly not in the U. S. While there may be some risk of government interference, it is not very likely to happen. Here is why: unlike in the 1930s, the U. S. dollar has become the world’s “reserve currency” today, with more dollars in circulation overseas than in the U. S. itself. Therefore, it would be extremely foolish for the U. S. government to “confiscate” gold as this might immediately raise suspicions worldwide about something being even more seriously wrong with the U. S. dollar than is generally accepted today and would very likely collapse the U. S. dollar within hours.
Most other ways of interference with the gold market would be as unlikely for the same reason.
Spreading scary news about “government confiscation” of gold is one ingredient of the better known gold scams and are normally used to get people to buying things they should not buy for the true reasons they set out on their original buying plan (like numismatic coins instead of bullion, see Can I Earn a higher Profit with Numismatics…, above). Successful investors develop a plan and stick with it. Do develop your plan and find out yourself how high the probability of gold “confiscation” really is. Once done, stick with your plan and be not fooled by some ignorant call center agent.
