Scott Morrison, Australia's Prime Minister, declared Sunday that for China to build a military base on the Solomon Islands is a "red line". He gave no detail away on how Australia would retaliate if Beijing were to build a base.

Both Washington and Canberra have been frantic about the Islands since Beijing and the Solomon Islands signed a security deal. The two, who've recently formed the nuclear-motivated AUKUS pact, deem the security deal "aggressive".

“Working together with our partners in New Zealand and of course the United States, I share the same red line that the United States has when it comes to these issues,” Morrison said. “We won’t be having Chinese military naval bases in our region on our doorstep.”

The Solomon Islands, situated about 2,000 km away from Australia, made international news last week when it signed a security treaty with China. A draft of the agreement was leaked recently, and it included Chinese promises of assistance in "maintaining social order." The agreement also allows Beijing to dock warships in the island's ports. Last year, the Islands experienced violent protests.
