US declares Beijing's South China Sea claims 'completely unlawful'; sanctions 20 PRC firms

In final days of outgoing US President Donald Trump’s administration, Secretary of State Mike Pompeo has openly declared Beijing's claims in South China Sea “completely unlawful” and sanctioned over 20 Chinese companies for "aiding" China's maritime claims.
