Seoul, May 25 : South Korea's Vice Defence Minister Shin Beom-chul has attended a virtual session of a US-led forum on support for war-torn Ukraine, his Ministry said. Hosted by US Secretary of Defence Lloyd Austin, Monday's session of the Ukraine Defence Contact Group involved officials from nearly 40 countries. Participants discussed the situation in Ukraine and joint efforts to aid the country, according to the Ministry on Tuesday. Shin condemned Russia's invasion of Ukraine as an "act that runs counter to the principle of the UN Charter" and explained Seoul's efforts to support the country, including its shipment of humanitarian and non-lethal aid, Yonhap news agency reported. He also said President Yoon Suk-yeol's administration will consider ways to make additional contributions "in consideration of our responsibilities and role as a global pivotal state". The Yoon administration has promoted the slogan "global pivotal state," in a show of its commitment to playing an active role in tackling regional and global challenges. The multilateral dialogue was launched in April to discuss effective ways of providing aid to Ukraine. Among the participating countries are Japan, New Zealand and members of the NATO. /IANS
