On June 1, 2026, at a China–Portuguese-speaking countries CBDC seminar in Macau,
China National Petroleum and Bank of China completed the first multilateral CBDC
bridge transaction between Macau and Hong Kong, which they said will boost
cross-border funding efficiency in the Guangdong-Hong Kong-Macao Greater Bay
Area. The companies also executed Macau's first 'currency bridge' CBDC transfer
to the UAE, opening a direct renminbi settlement channel into the Middle East.
