Plans are underway to welcome President Joe Biden back to San Diego for the second time in less than five months. The President will travel here on Monday. According to the White House, he'll be joined by the prime ministers of both Australia and the United Kingdom to talk about a security partnership the three have known as AUKUS. "This is a very, very important political and strategic event," said Tai Ming Cheung, a professor at UC-San Diego's School of Global Policy and Strategy. Cheung says the AUKUS pact includes agreements to buy and sell submarines and work together in the Indo-Pacific region. Specifically, Australia, which does not have its own industrial submarine base, will purchase nuclear submarines built and designed by the U.S. and UK at an estimated cost of $3 billion each. The U.S. will also be allowed to deploy their submarines in Australia.
