PHNOM PENH: Ukraine's foreign minister urged Southeast Asian countries on Saturday to take all possible measures to prevent Russia from engaging in "hunger games" over a Ukrainian Black Sea grain deal that could expire next week.

The deal allowing the export of food and fertilisers from several Ukrainian Black Sea ports, reached on July 22 by the UN and Turkey, could expire on November 19 if Russia or Ukraine object to its extension.

Ukraine Foreign Minister Dmytro Kuleba said at a news conference on the sidelines of the ASEAN summit in Cambodia that Russia's continued participation in the deal was insufficient and that steps should be taken to ensure that its inspectors were not purposefully delaying shipments and forcing global prices to rise.

"It is not enough to simply keep Russia on board. It is also critical to ensure that Russian inspectors who participate in this initiative act in good faith and inspect ships without artificial delays "He went on to say that countries in Africa and Asia were suffering.

"I urge all ASEAN members to use every available means to prevent Russia from playing hunger games with the rest of the world."

According to the UN, more than 10 million tonnes of grain and other food have been exported from Ukraine as part of the agreement. It has warned that Russia's war is exacerbating the global food crisis and driving tens of millions more people to starvation.

For the first time, Ukraine will attend the Association of Southeast Asian Nations (ASEAN) summit and a parallel East Asian Summit. US, Japanese, South Korean, and Australian leaders are among those in attendance, as is Russian Foreign Minister Sergei Lavrov.

According to Kuleba, Lavrov did not request a meeting with him during the summit, as is customary in international diplomacy.

"If he does," he said, "we will carefully consider his request," adding that Russia must approach all negotiations in good faith.

"There is not a single indicator that Russia is sincerely seeking negotiations," he said.

"We've been there, we've done it, we've tried sitting down at a table for a nice picture."

Kuleba stated that during meetings with Southeast Asian leaders, he discussed ways for them to support Ukraine and conveyed that expressing neutrality and not condemning Russia was detrimental to their interests.

"Nothing is the worst thing a country can do," he said.
