Unless the Singaporean entity uses its funds in a pro-russian manner, I'd consider this fairly isolated. Sanctions against Russia exist to hurt Russian economy and trade to punish and limit their war capacity. If the money stays outside and does not support the war, then I do not see an issue with a Russian citizen living abroad having an indirect controlling stake.
