On Wednesday's Backchat, we started off with Australian Prime Minister Anthony Albanese's recent state visit to China, his second in as many years. A number of trade agreements were signed and both sides agreed on the importance of deepening diplomatic and economic cooperation. We spoke to an expert about the significance of the trip.



We then learnt about a new, state-of-the-art device developed by the Chinese University of Hong Kong that treats a form of stroke.



After the break, we heard from a meteorologist on cloud seeding, a decades old weather modification technique -- and found out whether it's capable of triggering natural disasters. It came after rumours spread online that cloud seeding was to blame for the deadly flash floods in Central Texas earlier this month.



Finally, we wrapped up the programme by speaking to the Centre for Health Protection about Chikungunya fever-- a mosquito borne disease that's caused an outbreak in neighbouring Guangdong.
