This is the first time navies of both the countries conducted exercises in the East China Sea which separates China and Japan, official media here reported.
Two missile ships from each of their fleets took part in the exercises, state-run CCTV reported.
The exercises included anti-submarine drills, air defence, anti missile and mock confrontations. Commanders of China and Pakistan gave instructions in rotation.
The Pakistani naval ships Shamsheer and Nasr arrived in Shanghai on December 28 to take part in joint naval exercises in a bid to boost defence cooperation with their Chinese counterpart.
More than 100 countries and international organisation
gave their support for OBOR project and over 40 countries and international organisations signed agreements or letters of intent to join it, Lu said.
Officials say besides Trump, China was also keen on the participation of Prime Minister Narendra Modi.
But the Sino-Indian relations were bogged down by China blocking India's move to ban JeM leader Masood Azhar as a global terrorist by the UN like Saeed.
Over Azhar's issue, China also faced allegations from India of double standards in fighting terrorism.
Officials say it is to be seen how much of these issues would figure in China-Pakistan counter terror talks.
Also China is investing vast sums of money into the USD 46 billion China-Pakistan Economic Corridor (CPEC) which is part of the OBOR over which India has raised objections as it passed through Pakistan-occupied Kashmir (PoK).
China was also concerned about stepped up terror attack in its Muslim Uyghur majority Xinjiang province which is also the starting point for OBOR.
Afghan government too has raised strong pitch against Pakistan's reluctance to crackdown on the Haqqani network which is creating havoc in Afghanistan, scuttling all moves to restore peace in the war torn country.
