Russia state-owned technology company director general Rostec Sergey Chemezov was quoted by the Russian daily Kommersant: "The protracted talks on Su-35 deliveries to China have ended.

Indonesia agreed to invest KRW1.7tn ($1.47bn) in South Korea's Korean Fighter Experimental (KF-X) programme.
The KF-X is a KRW8.6tn ($7.5bn) project being developed by Korean Aerospace Industries (KAI), under a contract with the government. It is the second fighter development programme for the country after the FA-50.
KAI signed a contract with the Indonesian Government and state-run defence company Dirgantara Indonesia (PTDI).
Lockheed Martin is set to close a $9bn acquisition of Sikorsky Aircraft from United Technologies after the company received final regulatory approval from China.
According to Lockheed, the company anticipates closing the acquisition on 6 November.
The completion of the regulatory review by the China's Ministry of Commerce marks the end of a comprehensive regulatory review process in eight jurisdictions.
The US Air Force (USAF) ordered Northrop Grumman to stop work on the Long Range Strike-Bomber (LRS-B) after rivals, Boeing and Lockheed Martin, raised objections on the issuing of contract.
The matter is with the US Government Accountability Office (GAO), which is likely to announce its ruling by 16 February 2016.
Expected to be inducted into the USAF in the 2020s, the LRS-B is a heavy-payload stealth aircraft capable of carrying thermonuclear weapons.
The UK should join the coalition forces in airstrikes against the Islamic State of Iraq and the Levant (ISIL) in Syria, in order to deal with the threat posed by the terror outfit at home, Prime Minister David Cameron said.
Main threats against the UK are being planned in ISIL headquarters Raqqa, and it is there that the problem needs to be addressed, Cameron commented, while responding to the Foreign Affairs Select Committee's (FAC) report on the extension of UK military operations to Syria.
The country has been undertaking airstrikes on the outfit's strongholds in Iraq but has not yet ventured into Syria.

ULA Atlas and Delta programmes vice-president Jim Sponnick said: "GPS is omnipresent in our everyday lives and the system provides a critical service to all of those serving in our military around the world."
The US completed the development flight tests of the B61-12 nuclear gravity bomb, with the third and final test being undertaken by the National Nuclear Security Administration (NNSA) and the United States Air Force (USAF) at Tonopah Test Range in Nevada.
The tests would pave the way for production engineering in 2016.
An F-15E Strike Eagle multirole strike fighter from Nellis Air Force Base released the non-nuclear B61-12 bomb, which was manufactured by the National Security Enterprise Plants.
