Russia's Interfax news agency reported Sunday that British Foreign Secretary Catherine Beverley said that cooperation with China on climate change, economic stability, epidemic prevention and nuclear weapons proliferation must be strengthened, and that it is wrong to try to isolate China and cold war with China. At the same time, Britain will defend its national security interests. China is also expected to be held accountable if it violates its international obligations or human rights. He said China would be urged to be open about its claims and intentions for military expansion, as transparency is in everyone's interest, while secrecy only increases the risk of a tragic miscalculation.
