Since Russia barred imports of food from most of the rest of Europe, businesses are jostling for new buyers and sellers.
In the case of Knightsbridge Foods, its Russian supermarket clients may get spuds this winter not from Lincolnshire but from the Mediterranean island, where the crop from breakaway Turkish-speaking Northern Cyprus can be shipped via Turkey and so, the trader believes, evade Moscow's ban on European Union produce.
You need quick thinking, said Knightsbridge's owner, who declined to be identified by name before he visits the divided island, where the recognised government is an EU member. You need very strong contacts. Things change every single week.
Knightsbridge is one of many European firms exploring ways to sidestep Russia's import embargo on fruit, vegetables, meat, fish and dairy produce from the EU and Norway, as well as from the United States, Australia and Canada.
The ban, in retaliation for economic sanctions over the Ukraine crisis, could deny wealthy Russians delicacies like Norwegian smoked salmon, Italian ham and French cheese.
But, as with the communist nomenklatura in Soviet times, many expect the new elite will find ways to bypass customs controls not least as a waiver on shipments for personal use leaves a grey area for importing small, high-value cargoes.
Some firms expect more traffic to countries which maintain trading ties with Moscow, such as Turkey, and to neighbours like Belarus and Kazakhstan, which form a customs union with Russia.
Of course there's going to be a black market, said Luke Devlin, director of PDQ Specialist Couriers in Britain, which ships urgent products around Europe. They will still want their French ... cheese and they're still going to be able to get it.
In recent weeks there has been more interest in EU products from ex-Soviet Belarus and other eastern states, Devlin said, noting that logistics firms were considering ways to meet new demand. They've got established routes from the UK or France to Russia ... and they may as well see where they can build up.
A London-based stock analyst covering logistics companies said big, listed players which include Deutsche Post and Kuehne & Nagel would probably think twice about pouring too much new money into the region given the ban was likely to be temporary and the uncertainty of demand.
The waiver for personal use seems likely to promote some traffic between, say, St Petersburg and nearby Finland, from where shoppers can bring back small amounts of EU produce - and notably wine, vodka and other alcoholic drinks are not banned.
There are limits, however. Customs officers told Itar-Tass news agency they arrested a man driving home last week from Finland with 70 kg of French pheasant, duck and wild boar pate. Despite his claim that it was all for his own use, he was charged and faces a fine of up to twice the goods' value.
Russian officials also say they will be alert to large-scale importers trying to smuggle in embargoed goods via third countries. Exporters from Belarus will have to specify the country of origin of products when shipping goods onward to Russia, the agriculture ministry in Minsk told Reuters.
Nonetheless, at least one Belarussian trader saw room to manoeuvre: At the level of small imports it's a very simple scheme, to change the country of origin in the paperwork and to change the label to a Belarussian one, he said.
Of course an expert would spot it, he conceded. So the volume that gets through will depend on how much the Russian government is interested in stopping it.
Belarus and Kazakhstan said they will continue to import the foods Russia has banned but Minsk said it will stop them from travelling onward to Russia. Since the ban was announced, Russian media have joked that Muscovites will soon see supplies of oysters and shrimps from landlocked Belarus.
Russia and Belarus have clashed in the past over alleged abuses of their free trade agreement. For instance, Russia has accused Belarus of illegally re-exporting westward large volumes of refined products made from duty-free Russian oil.
(Russian) regulatory bodies can track the origin of goods when they are being sold, said a Russian official familiar with the rules of the customs union with Belarus.
And if goods that were not being supplied previously start to come from Belarus, it will be a signal to tighten checks.
