Chinese planes are usually a decade behind Russian planes in capability. Russia is a proven unreliable supplier. Saddam Hussein, Gaddafi, Iran, North Korea, China (in many cases) and even India were 'milked' for money to the extent that Russia could. Iran still can not purchase any modern fighter aircrafts from Russia because of American sanctions, not Russian sanctions. Is that a reliable supplier? Somebody was suggesting that Bangladesh might purchase about 80% of its fighter aircrafts from Russia, and that's never a politically sound decision.
Regarding ballistic missiles, the issue of USA retaliation can only arise if Bangladesh attacks. Otherwise, it can only be considered an act of American aggression. Ballistic missiles need not wait for good anti ship missiles or air defence, or vice versa. Also, Egypt pursued close ballistic missile cooperation with Iraq, Argentina, North Korea, to name a few. Egypt's Orascom Telecom is active in North Korea as it is active in Bangladesh (as Banglalink) or Pakistan (as Mobilink) or Iraq, and some other countries. That means Egypt moved in directions that suited its leadership, they need no other country's permissions.
China has already sold ballistic missiles to many countries including IRBMs to Saudi Arabia and has helped North Korea and Pakistan extensively in their missile programmes. If China declines to sell Bangladesh any ballistic missiles, that is a sign of failures in Bangladeshi diplomacy, nothing else.
BRO, Chinese aren't too far from Ruskies in A/C related know how. Please go over the following link to know that,

International Assessment and Strategy Center > Research > Report from the 2010 Chinese Defense Electronics Exhibition (CIDEX): Growing Industry – Advancing Technology (Chinese Defence Products Today: State-of-the Art
Chinese defence products were once thought of as being moderately capable copies of previous-generation hardware that contained attributes of Russian, European and Israeli designs. Some of those bloodlines can still be seen in their designs, but the products now being seen at an expo like CIDEX show that Chinese firms have capabilities that approach first world industrial, state-of-the-art levels of sophistication.
In the 1990s, when the Russian defence was in danger of drying up and closing its doors due to an almost complete collapse in any funding from their own government, it was China that saved the day. China bought billions in military hardware from Russia, but it also sent its engineers, designers and technicians to study inside of Russian industry to learn how the weapons it was purchasing had been developed in the first place.
This transfer of technological know-how, plus some enormous investments by the Chinese military into its state-owned industries (what more than one Russian has referred to as “uncontrolled and rampant modernisation”
has produced a defence electronics industry that far outstrips the size and capacity of that which existed in Russia when Chinese industry first began their cooperation with Moscow in the early 1990s.
Today the former students (the Chinese) have become the masters. Chinese industry now has the ability to produce components that the Russian electronics industry (after almost two decades of no investment by their government) is no longer capable of either designing or manufacturing. The initial failure rates on the production of transmit/receive (T/R) modules for the Active Electronically Scanned Array (AESA) radars being designed for the Mikoyan MiG-35 and the Sukhoi T-50/PAK-FA 5th-generation fighter, for example, were so high that it would have bankrupted any western firm involved in a similar programme.
Not surprisingly, this year’s CIDEX show saw groups of Russian specialists going through the halls and looking for components that they could source out of China to be utilised in Russian-designed weapon systems. Russian specialists will point out that they are now at a huge disadvantage to the Chinese in two very significant respects.
One is that the commitment by the central government in resources to the defence electronics sector is both sustained and serious. “They can take a field where there is nothing but flat land and wild grass,” said one Russian company representative, “and the next thing you know there is a full-blown factory or design centre there turning out a world-class product.”
Chinese firms are now producing components that far surpass that of the Russian firms they learned their skills from in the early 1990s.
The other advantage to China is the unfortunate reality of actuarial tables. Younger scientists and engineers who are needed in Russia to form the next-generation of weapons designers are leaving the nation in droves. A few years ago the Russian Foreign Intelligence Service (SVR) estimated that 70,000 scientists and specialists from Russian defence institutes and military-industrial complex enterprises had left the country.
A documentary on the subject produced by Moscow’s NTV stated “the nuclear physicists, experts in electronic equipment, virologists and biotechnologists did not leave Russia empty-handed. They took secrets with them and presented their former foes with the weapons they had themselves developed.”
The documentary went on to claim “according to CIA data, in the first half of the 1990s thousands of Soviet specialists in the field of nuclear and missile technology left for the Middle East. They worked there in violation of the treaty on non-proliferation of weapons of mass destruction and the MTCR. From the Arzamas-16 centre several people went to work in Iraq. Russian scientists worked in Iran and Libya. Forty nuclear scientists immigrated to Israel. Thousands of Russian specialists in the field of nuclear and missile technologies developed programmes to improve armaments in China. Our scientists are willing to work anywhere they are paid.”
The consequence is that whereas the age of the average defence industrial scientist or engineer in China is about 30 and around 40 in the US – it is 50 years or more in Russia. China’s industry is growing and advancing, while Russia’s will effectively be dying off before too long.)
