18 April, Euro MP Jacek Saryusz-Wolski, quoting the OSINTdefender account statedthat:
The Netherlands refuses to close its ports to Russian ships, violating EU law

The same false information quoted Law and Justice MP Anna April, suggesting that the Netherlands intends to break EU sanctions.

News that the Netherlands does not intend to block ports for Russian ships posted besides Radosław Poszwiński, a specialist in social media on TVP Info, and Jarosław Olechowski, Head of the tv Information Agency.

More about our evaluation system:Fifth package of European Union sanctions
8 March European Union announced 5th package of sanctions against Russia. The transport section states the following prohibition and its exceptions:
Prohibition of entry into EU ports of Russian-flagged vessels. Exemptions apply, among others, to medical, food, energy and humanitarian products.
On 13 April, Port Rotterdam announced that the port blockade for Russian ships would happen at midnight on Easter Sunday, i.e. on 17 April. How can we read in article on the portal pzc.nl, in On average, thirteen Russian ships arrived in Rotterdam last year. In the first 2 months of this year there were 29. According to the port spokesperson, all ships for which there is no exception, They had to leave port before Easter. Moreover, the ban applies not only to ships flying the Russian flag, but besides to Russian ships that changed the flag after February 24The day Russia invaded Ukraine.
Where does disinformation about Dutch ports come from?
How explainedOSINTdefender, disinformation came from the statements of the Dutch Prime Minister, Mark Rutte, on 9 March. However, as we read in article Reuters, Rutte was not about breaking the previously established day of EU sanctions, but to point out that the Netherlands cannot abandon Russian oil and gas imports overnight, which are inactive an exception in the 5th package of sanctions against Russia. So he repeated the same thing as the German Chancellor and Prime Minister Mateusz Morawiecki.
We gotta discuss our vulgarities in terms of our dependency on Russian oil and Russian gas. I would not pay for cutting off our supply of oil and gas from Russia today, it’s not possible due to the fact that we request the supply and that is the uncomfortable truth.

We request to discuss our weaknesses as regards dependence on Russian oil and Russian gas. I would not urge present to cut off oil and gas supplies from Russia, that is not possible due to the fact that we request these supplies and that is the uncomfortable truth.
Summary
It is not actual that Dutch ports have broken out of EU sanctions prohibiting the operation of Russian ships. EU government entered into force in all Dutch ports on 17 April at midnight. The exceptions to the Russian ships are clearly specified in the EU regulation. In addition, the Kingdom of the Netherlands undertook not to let Russian ships which changed their flag after 24 February.
Prime Minister Mark Rutte did not propose that the Kingdom of the Netherlands would not impose sanctions on the non-letting of Russian ships into its ports. It referred only to the inability to immediately abolish imports of gas and oil from Russia.
