HUMANITY is on the brink of "nuclear annihilation" with the threat reaching its highest boiling point in forty years, a top UN chief has warned.
The nuclear arms race has the globe teetering "unacceptably close" to mass atomic destruction, UN Secretary-General Antonio Guterres said.
He said: "The unconditional no first use is not suitable . . . unless China-US negotiations agree that neither side would use [nuclear weapons] first, or the US will no longer take any passive measures to undermine the effectiveness of China’s strategic forces.
"The strategic pressure on China is intensifying as (the US) has built new military alliances and as it increases its military presence in our neighbourhood."
Meanwhile, tensions have been mounting with China sending fighter jets to Taiwan after the self-governing island announced its intention to join an 11-nation Pacific trade group that Beijing has also applied to join.
"The Chinese Communists have continued to invest heavily in national defence budgets, its military strength has grown rapidly, and it has frequently dispatched aircraft and ships to invade and harass our seas and airspace," Taiwan's Defence Ministry said.
"In the face of severe threats from the enemy, the nation's military is actively engaged in military building and preparation work, and it is urgent to obtain mature and rapid mass production weapons and equipment in a short period of time."
Taiwan has already unveiled a class of highly agile stealth warships, which it refers to as an "aircraft carrier killer", and it's also developing its own submarines.
