-In early April incidents near Parcel island(disputed with Vietnam),in this particular incident Chinese coastguard deliberately crashed and sunk the Vietnamese boat and in past also similar aggression has been shown by the Chinese navy and coastguard.
-The Natanu islands(disputed with Indonesia),it has emerged as new dispute between China and Indonesia,recently the Chinese fishing vessel backing of Chinese coast guard have indulge in illegal fishing.
-Kagitman Reef and Zamora Reef(disputed with Philippines)in this the satellite image have shown landing of Chinese military plane in disputed Kagitangan Reef.According to research,China has deployed research military centers at these two islands.
These increased military aggression by China during this pandemic in South China Sea,and their claim in East China Sea over the disputed islands which Japan has sovereign rights is aggravated.Apart from their vague historical claims there is one more thing that they might be showing their aggression against is USA.Over the years USA has developed itself a key player in South China Sea,following these developments,the USA has also criticized China for its aggressive moves.China knows that these moves,are going to affect its close relationship with South East Countries and its globally nurtured image,but if its going with its strategy it means,that it is trying to take advantage of the window of the opportunity created by the pandemic.
This could be also China's reaction to express its displeasure against FONOPS that USA recently conducted with Vietnam. FONOPS(FONOPS) means(freedom of navigation operation).It is a joint exercise conducted by USA in South China Sea and its allies to counter China.These naval operation by USA has always been criticized by China and may be expressing its displeasure by the naval exercises which are conducted by USA.
