Russia and China have found a workaround for payments as US sanctions expand, according to sources, Reuters reports. The sanctions, which recently targeted the only Russian bank branch in China, have narrowed trade options between the two countries. However, President Vladimir Putin's visit to China last month has helped ensure there are payment alternatives. Intermediaries for payments to China have increased their charges to Russian companies from 3-6% to 10% of the invoiced amount since the start of the year. China's yuan is expected to take over as Russia's main trade currency as US sanctions tighten. China opposes unilateral sanctions and maintains its right to normal trade and economic ties with Russia based on equality and mutual benefit.
