Gallium prices in China have dropped 12% this year, pressured by its slowing economy.
China's germanium ingot price has advanced only 1% to 7,250 yuan per kg since Monday.
Overseas price offers are rising much faster, amid fears that Beijing may use the permitting system to restrict shipments.
The Chinese government enforces export controls that do not target any particular country," spokesperson Shu Jueting told a weekly press conference.
China produces around 60% of the world's germanium, and over 90% of the world's gallium.
