Input: Consider Input: “Without the reference to a June review  Russia would have been tied to the end of 2018; it wanted instead to have an escape clause ”  Petromatrix strategist Olivier Jakob  said.
“It leaves a question mark about the second half [of 2018] and about the commitment of Russian oil companies  which will be price dependent ”  he  said.
The CEO of Russia’s top private producer Lukoil told Reuters  he  would like to see the price of oil stable at current levels  trading in the $60-65 per barrel range.
The oil market is unlikely to overheat   he  added  thanks to cooperation between OPEC and its allies which would allow them to release new output into the market to rebalance it.

Input: Consider Input: MURDEROUS  thin-skinned and in possession of nuclear weapons  the North Korean dictator   Kim Jong Un   has one good deed to  his  name:  he  has united America and China. Max Baucus  Americaâs ambassador to Beijing until January 2017  recalls the Chinese president  Xi Jinping  privately expressing âdisgustâ at Mr Kimâs reckless pursuit of nukes and missiles to carry them to other continents. Mr Xiâs frustration with North Koreaâs hereditary despot stands out as âthe strongest statement that I have ever heard Xi makeâ  says Mr Baucus. China has never sounded as closely aligned with America when it comes to using sanctions and diplomatic pressure  in a last-ditch bid to change how Mr Kim calculates his regimeâs interests.
Unfortunately for relations between the worldâs two biggest economies  China will hate the next steps that America is likely to take on North Korea. Evan Medeiros  until 2015 the senior director for Asia in Barack Obamaâs National Security Council  says that when the Chinese accuse America of refusing to engage in talks with the regime  this is largely âposturingâ. But behind it lies a truth  that âsanctions wonât stop North Koreaâ. When battling the proliferation of the deadliest weapons  sanctions are always in a race with technology  says Mr Medeiros  now with the Eurasia Group  a consultancy. âKim Jong Un is close to grasping the brass ring. We have probably lost the race and need to think about deterrence.â This could include deploying new missiles and missile-defence systems in South Korea and Japan  and perhaps another aircraft-carrier in the region.
Still  cold-war theories of deterrence are being dusted off  with such jargon as âsecond-strike capabilityââthe certainty that a country attacked with nuclear weapons can retaliate massively. Douglas Paal  a senior Asia hand in the Reagan White House and both Bush administrations  approves of the Senate plan to place more interceptors in Alaska  in part to gain leverage over China. âWe need to layer up more missile defence. China needs to see that their second-strike capacity is really deteriorating  which hurts them.â Mr Paal  who runs the Asia programme at the Carnegie Endowment for International Peace  a think-tank  is in frequent contact with envoys of governments including Chinaâs and  recently  North Koreaâs. He concedes the need for talks with the  Kim  regime  alongside containment and deterrence  but notes that in previous negotiations  North Korea wanted an end to American defence alliances in Asia and to Americaâs troop presence in South Korea: âSo we canât get there.â
A policy of containment would not just strain relations with China as new American weapons bristled in Asia. Global non-proliferation regimes would be tested  not least because a North Korea facing crippling sanctions might see selling nuclear technology as a lifeline. Perhaps Chinaâs greatest nightmare involves Japan feeling compelled to build nuclear weapons (it could quickly develop the technology). A Chinese build-up of warheads in response could result in India and then Pakistan increasing their stockpiles. The unity fostered by  Mr Kim  may thus prove short-lived. If  he  builds the arsenal  he  wants  China and America will be sincere in their shared dismay. But if America then prepares to contain him  a whole new Sino-American stand-off may begin.
